Differential Elliptic Flow Analysis Of Hadrons With Different Wuark Content In Simulated Pp Collisions, Elhussein Osama 2024 American University in Cairo

Differential Elliptic Flow Analysis Of Hadrons With Different Wuark Content In Simulated Pp Collisions, Elhussein Osama

Theses and Dissertations

According to current physics theories, it is assumed that in the first microsecond after the big bang, the universe was in a state of matter called Quark-Gluon Plasma (QGP), where the fundamental consistent of matters (quarks and leptons), were highly energetic, and floating around freely. Searching for such phase of matter; as the possible earliest signatures after the big bang, and among many other interesting experimental measurements, the jet quenching and elliptic flow are the most important ones, in the heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) experiments.

Beyond Standard Model: Axial Electric Potentials Of Quarks And Neutrinos, Polievkt Perov 2024 Suffolk University

Beyond Standard Model: Axial Electric Potentials Of Quarks And Neutrinos, Polievkt Perov

College of Arts & Sciences Faculty Works

The equations of axial electric potentials are presented for our models of quarks and neutrinos as spinning composite structures where up to 3 basic elementary charges are on the axis or rotation and the other N charges are revolving about the axis. The axial potential functions at given point on the axis of rotation were calculated as the sum of electric potentials at that point from all the charges in the structure. We applied these general equations specifically to the models of two types of neutral particles (neutrinos), one with 2 like charges on the axis and the other with …

From Norms Taker To Norms Breaker: A Comparative Study Of Turkey’S Nuclear Discourses Before And After The Ostensible Coup Of 2016, Sarah Tzinieris, Zenobia S. Homan, Cem Boke, Amna Javed

International Journal of Nuclear Security

This article offers an analysis of public statements made by Turkish government leaders, contrasting official attitudes on nuclear nonproliferation before and after the alleged military coup attempt in 2016. Significant developments in this period include deteriorating democracy and the rule of law in Turkey and the emergence of destabilizing foreign policy differences between Turkey and Western states. President Recep Tayyip Erdoğan also sought to consolidate domestic power and play a more assertive security role in the Middle East. This analysis of official statements reveals a distinct shift in Turkey’s nonproliferation rhetoric after the 2016 coup. In particular, Turkish government ministers …


Beyond Standard Model: Structure Factors Of Models Of Different Quarks And Neutrinos As Spinning Structures Made Of Basic Fractional Charges +- E/3, Polievkt Perov 2024 Suffolk University

Beyond Standard Model: Structure Factors Of Models Of Different Quarks And Neutrinos As Spinning Structures Made Of Basic Fractional Charges +- E/3, Polievkt Perov

College of Arts & Sciences Faculty Works

We consider a possible line of “elementary” particles as composite spinning structures made of just two basic elementary particles of charges + e/3 and -e/3. In considered structures, up to 3 basic charges can be on the axis of rotation and other charges can be in a revolving motion about the axis. In addition to the simplest structures of quarks, an electron and a neutral particle containing mostly one or no charges on the axis of rotation, suggested initially in [4], we analyze possible spatial structures of spinning composite particles having 2 or 3 charges on the axis of rotation. …

The electronic structure and translucent nature of lithium tetraborate (Li2B4O7) render it promising as a scintillator medium for neutron detection applications. The inherently large neutron capture cross-section due to 10B and 6Li isotopes and the ease with which Li2B4O7 can be enriched with these isotopes, combined with the facile inclusion of rare earth dopants (occupying the Li+ sites), are expected to improve the luminescent properties, as well as the neutron detection efficiency, of Li2B4O7. The electronic structure of both doped …


Beyond Standard Model: Electromagnetic Origin Of Strong Interaction Between Composite Structures Made Of Basic Elementary ±E/3 Charges, Polievkt Perov 2023 Suffolk University

Beyond Standard Model: Electromagnetic Origin Of Strong Interaction Between Composite Structures Made Of Basic Elementary ±E/3 Charges, Polievkt Perov

College of Arts & Sciences Faculty Works

Interaction between spinning composite structures of quarks is considered. In simple variants of the quark structures, one basic elementary particle of charge of magnitude |e|/3 is on the axis of rotation and several basic particles of an opposite sign are revolving in the circular orbit about the axis. Each charge in the structure contributes to the electric field and electric potential around the structure. But only revolving basic particles contribute to the spin and to the magnetic moment of the structure. Equations for the axial electric field and the electric potential of each structure at points on its axis are …

Multiple Genre Argument

Research in progress for ENGL 1301: Composition I

Faculty Mentor: W. Scott Cheney, Ph.D.

Standard research papers and five-paragraph essays can train students to blend quotations and organize paragraphs, but advanced writing in the disciplines and the workplace requires much more robust and nuanced thinking. To this end, the Multiple Genre Argument (MGA) pushes students into new writing situations where they create fictional genres to supplement traditional research—a challenging and often confusing task. Learning new skills requires becoming more comfortable with encountering this kind of difficulty and uncertainty. In their book Writing Analytically, David Rosenwasser and Jill …


Characterization Of Isomeric States In Neutron-Rich Nuclei Approaching N = 28, Timilehin Hezekiah Ogunbeku 2023 Mississippi State University

Characterization Of Isomeric States In Neutron-Rich Nuclei Approaching N = 28, Timilehin Hezekiah Ogunbeku

Theses and Dissertations

The investigation of isomeric states in neutron-rich nuclei provides useful insights into the underlying nuclear configurations, and understanding their occurrence along an isotopic chain can inform about shell evolution. Recent studies on neutron-rich Si isotopes near the magic number N = 20 and approaching N = 28 have revealed the presence of low-lying states with intruder configurations, resulting from multiple-particle, multiple-hole excitations across closed shell gaps. The characterization of these states involves measuring their half-lives and transition probabilities.

In this study, a new low-energy (7/21) isomer at 68 keV in 37Si was accessed via beta decay …

Linear regression analysis was performed to determine if there were significant differences between the intercepts of the …


Short Range Correlation Measurements In The Quasielastic Region With An 11 Gev Beam, Casey Morean 2023 University of Tennessee, Knoxville

Short Range Correlation Measurements In The Quasielastic Region With An 11 Gev Beam, Casey Morean

Doctoral Dissertations

Electron scattering is a significant means of studying internal high momentum
nucleon and quark distributions in nuclei. Thomas Jefferson National Accelerator
Facility (JLab) with its 11GeV beam is capable of studying high momentum nucleons
with unmatched precision. The role of short range nucleon configurations and
quark distributions is significant for understanding the dynamics of nuclei and their
underlying components. Scattering cross section measurements in the kinematic
regime x > 1, where the free nucleon is forbidden, are sensitive to high momentum
nucleons, which are believed to come from short range correlations (SRCs). SRCs are
strongly interacting, high momentum nucleons with a …

Tev-Scale Lepton Number Violation: 0Νββ Decay, The Origin Of Matter, And Energy Frontier Probes, Sebastian Urrutia Quiroga

Doctoral Dissertations

Lepton number violation (LNV) offers promising theoretical pathways to several unresolved problems in particle and nuclear physics and unveils a diverse range of phenomenology across different energy scales. TeV-scale LNV is especially relevant for both its experimental accessibility and its broad-ranging impact, making it a key area of interest for both theoretical and experimental physicists. In this thesis, we explore three distinct scenarios within the LNV research landscape. Our first analysis concerns the implications of TeV-scale LNV effects in thermal leptogenesis and its complementary sensitivity in neutrinoless double beta (0νββ) decay and collider experiments. We employed a simplified model to …

Perception Of Nuclear Security As A Barrier To Female Representation In Africa, Primerose Ruhukwa Ms 2023 Radiation Protection Authority of Zimbabwe

Perception Of Nuclear Security As A Barrier To Female Representation In Africa, Primerose Ruhukwa Ms

International Journal of Nuclear Security

Women are strongly underrepresented in the nuclear energy sector, particularly in the field of Nuclear security. Regardless of several government efforts to increase the number of women in this field, which include gender balance polices, education, and awareness campaigns, the nuclear security industry remains a male-dominated field. The reason why nuclear security is shunned by most women in Africa is because of an incorrect perception of what nuclear security is. When a lay person hears the term nuclear, the first thing that comes to mind is nuclear weapons, and many are quick to judge, saying that Africa does not …

Dissertations, Theses, and Capstone Projects

Hadrons created in heavy-ion collisions interact with the open color-charge of the quark-gluon plasma through their constituent quarks. The medium imparts substantial modifications to heavy-flavor hadrons' momentum spectra. For collisions of small systems, the centrality of those collisions affects both the production of heavy-quarks and the medium modifications that the heavy-quarks experience. This analysis uses the PHENIX detector at the Relativistic Heavy Ion Collider, which collected data from proton--gold collisions in 2015, with a trigger to preference the collection of the five-percent most-central collisions. This analysis uses the distance-of-closest-approach of electron tracks to study semileptonic decays from charm and bottom …


Phase Transitions And Thermal Stability Of The Magnetic Dual Chiral Density Wave Phase In Cold, Dense Qcd, William G. Gyory 2023 The Graduate Center, City University of New York

Phase Transitions And Thermal Stability Of The Magnetic Dual Chiral Density Wave Phase In Cold, Dense Qcd, William G. Gyory

Dissertations, Theses, and Capstone Projects

The correct description of strongly interacting matter at extreme densities and low temperatures remains poorly understood. We analyze the magnetic dual chiral density wave (MDCDW) phase, an inhomogeneous chiral condensate that arises in cold, dense quark matter in a magnetic field. We first review the background theory and derive the free energy of the condensate. Then we show how the phase transitions can be studied using a generalized Ginzburg-Landau expansion, and we derive a convenient all-orders formula for the coefficients. Using these tools, we compute the order parameters, critical temperature, and threshold temperature over a range of chemical potentials and …
