Discontinuous Phase Transitions In Nonlocal Schloegl Models For Autocatalysis: Loss And Reemergence Of A Nonequilibrium Gibbs Phase Rule, DaJiang Liu, ChiJen Wang, James W. Evans
Discontinuous Phase Transitions In Nonlocal Schloegl Models For Autocatalysis: Loss And Reemergence Of A Nonequilibrium Gibbs Phase Rule, DaJiang Liu, ChiJen Wang, James W. Evans
James W. Evans
We consider Schloegl models (or contact processes) where particles on a square grid annihilate at a rate p and are created at a rate of kn=n(n−1)/[N(N−1)] at empty sites with n particles in a neighborhood ΩN of size N. Simulation reveals a discontinuous transition between populated and vacuum states, but equistable p=peq determined by the stationarity of planar interfaces between these states depends on the interface orientation and on ΩN. The behavior for large ΩN follows from continuum equations. These also depend on the interface orientation and on ΩN shape, but a unique ...

PHENIX reports differential cross sections of mu mu pairs from semileptonic heavyflavor decays and the DrellYan production mechanism measured in p + p collisions at root s = 200 GeV at forward and backward rapidity (1.2 < vertical bar eta vertical bar < 2.2). The mu mu pairs from c (c) over bar, b (b) over bar, and DrellYan are separated using a template fit to unlike and likesign muon pair spectra in mass and p(T). The azimuthal opening angle correlation between the muons from c (c ) over bar and b (b) over bar decays and the pairp(T) distributions are compared to distributions generated using PYTHIA and POWHEG models, which both include nexttoleading order processes. The measured distributions for pairs from a are consistent with PYTHIA calculations. The c (c) over bar data present narrower azimuthal correlations and softer p(T) distributions compared to distributions generated from POWHEG. The b (b ) over bar data are well described by both models. The extrapolated total cross section for bottom production is 3.75 +/ 0.24(stat) +/(0.35)(0.50) (syst) +/ 0.45(global) [mu b], which is consistent with previous measurements at the Relativistic Heavy Ion Collider in the same system at the same collision energy and is approximately a factor of 2 higher than the central value calculated with theoretical models. The measured DrellYan cross section is in good agreement with nexttoleadingorder quantumchromodynamics calculations.

Measurements of the differential production of electrons from openheavyflavor hadrons with charm and bottomquark content in p+p collisions at √s=200 GeV are presented. The measurements proceed through displacedvertex analyses of electron tracks from the semileptonic decay of charm and bottom hadrons using the PHENIX siliconvertex detector. The relative contribution of electrons from bottom decays to inclusive heavyflavorelectron production is found to be consistent with fixedorderplusnexttoleadinglog perturbativeQCD calculations within experimental and theoretical uncertainties. These new measurements in p+p collisions provide a precision baseline for comparable forthcoming measurements in A+A collisions.

Asymmetric nuclear collisions of p+Al, p+Au, d+Au, and 3He+Au at √sNN=200 GeV provide an excellent laboratory for understanding particle production, as well as exploring interactions among these particles after their initial creation in the collision. We present measurements of charged hadron production dNch/dη in all such collision systems over a broad pseudorapidity range and as a function of collision multiplicity. A simple wounded quark model is remarkably successful at describing the full data set. We also measure the elliptic flow v2 over a similarly broad pseudorapidity range. These measurements provide key constraints on models ...
SingleSpin Asymmetry Of J/Ψ Production In P+P, P+Al, And P+Au Collisions With Transversely Polarized Proton Beams At √Snn=200 Gev, C. Aidala, Nicole J. Apadula, John C. Hill, Nels J. Hotvedt, John G.

We report the transverse singlespin asymmetries of J/ψ production at forward and backward rapidity, 1.2<y<2.2, as a function of J/ψ transverse momentum (pT) and Feynmanx (xF). The data analyzed were recorded by the PHENIX experiment at the Relativistic Heavy Ion Collider in 2015 from p+p, p+Al, and p+Au collisions with transversely polarized proton beams at √sNN=200 GeV. At this collision energy, singlespin asymmetries for heavyflavor particle production of p+p collisions provide access to the spindependent gluon distribution and highertwist correlation functions inside the nucleon, such as the gluon QiuSterman and trigluon correlation functions. Proton+nucleus collisions offer an excellent opportunity to study nuclear effects on the correlation functions. The data indicate a positive asymmetry at the twostandarddeviation level in the p+p data for 2 GeV/c
Measurement Of ΦMeson Production At Forward Rapidity In P+P Collisions At √S=510 Gev And Its Energy Dependence From √S=200 Gev To 7 Tev, A. Adare, Nicole J. Apadula, Sarah C.

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section of phi(1020)meson production at forward rapidity in p + p collisions at root s = 510 GeV via the dimuon decay channel. The partial cross section in the rapidity and PT ranges 1.2 < vertical bar y vertical bar < 2.2 and 2 < p(T) < 7 GeV/c is sigma(phi) = [2.28 +/ 0.09(stat) +/ 0.14(syst) +/ 0.27(norm)] x 10(2) mb. The energy dependence of sigma(phi) (1.2 < vertical bar y vertical bar < 2.2,2 < p(T) < 5 GeV/c) is studied using the PHENIX measurements at root s = 200 and 510 GeV and the Large Hadron Collider measurements atroot s = 2.76 and 7 TeV. The experimental results arc compared to various event generator predictions (PYTHIA6, PYTHIA8, PHOJET, AMPT, EPOS3, and EPOSLHC).

We have measured the cross section and singlespin asymmetries from forward W±→μ±ν production in longitudinally polarized p+p collisions at √s=510 GeV using the PHENIX detector at the Relativistic Heavy Ion Collider. The cross sections are consistent with previous measurements at this collision energy, while the most forward and backward longitudinal single spin asymmetries provide new insights into the sea quark helicities in the proton. The charge of the W bosons provides a natural flavor separation of the participating partons.

Experimental studies of the collisions of heavy nuclei at relativistic energies have established the properties of the quark–gluon plasma (QGP), a state of hot, dense nuclear matter in which quarks and gluons are not bound into hadrons 1–4 . In this state, matter behaves as a nearly inviscid fluid 5 that efficiently translates initial spatial anisotropies into correlated momentum anisotropies among the particles produced, creating a common velocity field pattern known as collective flow. In recent years, comparable momentum anisotropies have been measured in smallsystem proton–proton (p+p) and proton–nucleus (p+A) collisions, despite expectations that the ...

In this review we examine the influence of the line tension s on droplets and particles at surfaces. The line tension influences the nucleation behavior and contact angle of liquid droplets at both liquid and solid surfaces and alters the attachment energetics of solid particles to liquid surfaces. Many factors, occurring over a wide range of length scales, contribute to the line tension. On atomic scales, atomic rearrangements and reorientations of submolecular components give rise to an atomic line tension contribution satom (1 nN), which depends on the similarity/dissimilarity of the droplet/particle surface composition compared with the surface ...

Fluctuations In A Cosmology With A Spacelike Singularity And Their Gauge Theory Dual Description, Robert H. Brandenberger, Elisa G.M. Ferreira, Ian A. Morrison, YiFu Cai, Sumit R. Das, Yi Wang
Ian Morrison
We consider a timedependent deformation of anti–de Sitter (AdS) spacetime which contains a spacelike “singularity”—a spacelike region of high curvature. Making use of the AdS/CFT correspondence we can map the bulk dynamics onto the boundary. The boundary theory has a time dependent coupling constant which becomes small at times when the bulk spacetime is highly curved. We investigate the propagation of small fluctuations of a test scalar field from early times before the bulk singularity to late times after the singularity. Under the assumption that the AdS/CFT correspondence extends to deformed AdS spacetimes, we can map ...

Holographic Renormalization Of Asymptotically Lifshitz Spacetimes, Robert Mcnees, Robert Mann
Robert A McNees IV
A variational formulation is given for a theory of gravity coupled to a massive vector in four dimensions, with Asymptotically Lifshitz boundary conditions on the fields. For theories with critical exponent z=2 we obtain a welldefined variational principle by explicitly constructing two actions with local boundary counterterms. As part of our analysis we obtain solutions of these theories on a neighborhood of spatial infinity, study the asymptotic symmetries, and consider different definitions of the boundary stress tensor and associated charges. A constraint on the boundary data for the fields figures prominently in one of our formulations, and in that ...

Black Holes In The Conical Ensemble, Robert Mcnees, Daniel Grumiller
Robert A McNees IV
We consider black holes in an “unsuitable box”: a finite cavity coupled to a thermal reservoir at a temperature different than the black hole’s Hawking temperature. These black holes are described by metrics that are continuous but not differentiable due to a conical singularity at the horizon. We include them in the Euclidean path integral sum over configurations, and analyze the effect this has on black hole thermodynamics in the canonical ensemble. Black holes with a small deficit (or surplus) angle may have a smaller internal energy or larger density of states than the nearby smooth black hole, but ...

Boundary Terms Unbound! Holographic Renormalization Of Asymptotically Linear Dilaton Gravity, Robert Mcnees, Robert Mann
Boundary Terms Unbound! Holographic Renormalization Of Asymptotically Linear Dilaton Gravity, Robert Mcnees, Robert Mann
Robert A McNees IV
A variational principle is constructed for gravity coupled to an asymptotically linear dilaton and a pform field strength. This requires the introduction of appropriate surface terms—also known as 'boundary counterterms'—in the action. The variation of the action with respect to the boundary metric yields a boundary stress tensor, which is used to construct conserved charges that generate the asymptotic symmetries of the theory. In most cases a minimal set of assumptions leads to a unique set of counterterms. However, for certain examples we find families of actions that depend on one or more continuous parameters. We show that ...

We study the embedding of flat BPS 3branes in five dimensional N=2 supergravity theory. We derive the branes' dynamical equations as well as general expressions for the hypermultiplet fields then focus on a single brane and study its time evolution. It is shown that the brane's Hubble parameter correlates with the moduli of the underlying manifold's complex structure. For certain particular solutions, the moduli seem to exhibit an instability; being large valued at early times then rapidly decaying to either zero or some convergent constant value. The possibility of extending these results to the cosmology of our ...
Lorentz Violation With An Antisymmetric Tensor, Brett Altschul, Quentin G. Bailey, V. Alan Kostelecky
Lorentz Violation With An Antisymmetric Tensor, Brett Altschul, Quentin G. Bailey, V. Alan Kostelecky
Quentin Bailey
Field theories with spontaneous Lorentz violation involving an antisymmetric 2tensor are studied. A general action including nonminimal gravitational couplings is constructed, and features of the Nambu Goldstone and massive modes are discussed. Minimal models in Minkowski spacetime exhibit dualities with Lorentzviolating vector and scalar theories. The postNewtonian expansion for nonminimal models in Riemann spacetime involves qualitatively new features, including the absence of an isotropic limit. Certain interactions producing stable Lorentzviolating theories in Minkowski spacetime solve the renormalizationgroup equations in the tadpole approximation.
LorentzViolating Gravitoelectromagnetism, Quentin G. Bailey
LorentzViolating Gravitoelectromagnetism, Quentin G. Bailey
Quentin Bailey
The wellknown analogy between a special limit of general relativity and electromagnetism is explored in the context of the Lorentzviolating standardmodel extension. An analogy is developed for the minimal standardmodel extension that connects a limit of the CPTeven component of the electromagnetic sector to the gravitational sector. We show that components of the postNewtonian metric can be directly obtained from solutions to the electromagnetic sector. The method is illustrated with specific examples including static and rotating sources. Some unconventional effects that arise for Lorentzviolating electrostatics and magnetostatics have an analog in Lorentzviolating postNewtonian gravity. In particular, we show that even ...
Limits On Violations Of Lorentz Symmetry From Gravity Probe B, Quentin G. Bailey, Ryan D. Everett, James M. Overduin
Limits On Violations Of Lorentz Symmetry From Gravity Probe B, Quentin G. Bailey, Ryan D. Everett, James M. Overduin
Quentin Bailey
Generic violations of Lorentz symmetry can be described by an effective field theory framework that contains both general relativity and the Standard Model of particle physics called the StandardModel extension (SME). We obtain new constraints on the gravitational sector of the SME using recently published final results from Gravity Probe B. These include for the first time an upper limit at the 10_3 level on the timetime component of the new tensor field responsible for inducing local Lorentz violation in the theory, and an independent limit at the 10_7 level on a combination of components of this tensor field.
TimeDelay And Doppler Tests Of The Lorentz Symmetry Of Gravity, Quentin G. Bailey
TimeDelay And Doppler Tests Of The Lorentz Symmetry Of Gravity, Quentin G. Bailey
Quentin Bailey
Modifications to the classic timedelay effect and Doppler shift in general relativity (GR) are studied in the context of the Lorentzviolating standardmodel extension (SME). We derive the leading Lorentz violating corrections to the timedelay and Doppler shift signals, for a light ray passing near a massive body. It is demonstrated that anisotropic coefficients for Lorentz violation control a timedependent behavior of these signals that is qualitatively different from the conventional case in GR. Estimates of sensitivities to gravitysector coefficients in the SME are given for current and future experiments, including the recent Cassini solar conjunction experiment.

LightBending Tests Of Lorentz Invariance, Quentin G. Bailey, Rhondale Tso
Quentin Bailey
Classical lightbending is investigated for weak gravitational fields in the presence of hypothetical local Lorentz violation. Using an effective field theory framework that describes general deviations from local Lorentz invariance, we derive a modified deflection angle for light passing near a massive body. The results include anisotropic effects not present for spherical sources in General Relativity as well as Weak Equivalence Principle violation. We develop an expression for the relative deflection of two distant stars that can be used to analyze data in past and future solarsystem observations. The measurement sensitivities of such tests to coefficients for Lorentz violation are ...

Dark Matter As An Integral Part Of An Alternative Gravity Model, Hontas Farmer
Hontas F Farmer
The purpose of this paper is to reconcile observations of dark matter effects on the galactic and cosmological scales with the null results of astroparticle physics observations such as CDMS and ANTARES. This paper will also provide a candidate unified and simpler mathematical formulation for the Lambda CDM model. Unification is achieved by a combination of the f(R) approach, with the standard LCDM approach and inflationary models. It is postulated that dark matterenergy fields depend on the Ricci curvature R. Standard methods of classical and quantum field theory on curved space time are applied. When this model is treated ...

Conformal Gravity Holography In Four Dimensions, Robert Mcnees
Robert A McNees IV
We formulate fourdimensional conformal gravity with (anti–)de Sitter boundary conditions that are weaker than Starobinsky boundary conditions, allowing for an asymptotically subleading Rindler term concurrent with a recent model for gravity at large distances. We prove the consistency of the variational principle and derive the holographic response functions. One of them is the conformal gravity version of the Brown–York stress tensor, the other is a “partially massless response”. The on shell action and response functions are finite and do not require holographic renormalization. Finally, we discuss phenomenologically interesting examples, including the most general spherically symmetric solutions and rotating ...

Background: The Lambda CDM model or is the standard model of modern cosmology. It is named for dark energy and cold dark matter. This model contains a number of separate components with different mathematical formulations. Strong observational evidence for dark matter has been found by astronomy. At the same time astroparticle physics observations have not found solid evidence of dark matter. Purpose: The purpose of this paper is to reconcile observations of dark matter effects on the galactic and cosmological scales with the null results of astroparticle physics observations such as CDMS and ANTARES. This paper will also provide a ...
