Heavy flavor quarks are produced early in heavy ion collisions and will experience the full evolution of the Quark Gluon Plasma (QGP). Measurements at forward rapidity may be influenced as much, or more, by the cold nuclear matter effects as by the hot nuclear matter effects associated with a QGP. As the medium evolves, the initial spatial anisotropy of participants is converted to an azimuthal anisotropy in the momentum space of outgoing particles. Therefore, the momentum spectra modification and anisotropy parameters provide useful information about the heavy quark interaction with the bulk medium.
Asymmetric heavy ion collisions, such as Cu+Au, …

Heavy-ion collisions at LHC energies create a hot and dense medium of deconned quarks
and gluons, known as the quark-gluon plasma (QGP) [56]. The QGP reball rst expands,
cools and then freezes out into a collection of nal-state hadrons. Correlations between the
free particles carry information about the space-time extent of the emitting source, and are
imprinted on the nal-state spectra due to a quantum-mechanical interference eect [18].
The correlation of two identical particles at small relative momentum, commonly known as
intensity, or Hanbury Brown-Twiss (HBT), interferometry, is an eective tool to study the
space-time structure of the emitting source …

A data-driven method was applied to Au+Au collisions at √Sɴɴ = 200 GeV made with the STAR detector at RHIC to isolate pseudorapidity distance Δ η-dependent and Δ η-independent correlations by using two- and four-particle azimuthal cumulant measurements. We identified a Δ η-independent component of the correlation, which is dominated by anisotropic flow and flow fluctuations. It was also found to be independent of η within the measured range of pseudorapidity | η | < 1. In 20-30% central Au+Au collisions, the relative flow fluctuation was found to be 34% ± 2%(stat.) ± 3%(sys.) for particles with transverse momentum pT less than 2 GeV/c. The Δ η-dependent part, attributed to nonflow correlations, is found to be 5% ± 2%(sys.) relative to the flow of the …

Quantum Chromodynamics, which describe the interactions of quarks and gluons, have been found not to violate global parity symmetry. However, the possibility
of local parity violations due to transitions in the vacuum state of QCD is not excluded. The effects of these parity violations could be measured in the
hot and dense medium created in the ultrarelativistic heavy ion collisions experiment conducted at the Large Hadron Collider, called a Quark-Gluon Plasma, in which
the quarks that compose most of ordinary matter are deconfined. In the strong magnetic fields which permeate the QGP in non-central collisions, parity violation
would express itself …
