In ultrarelativistic heavy-ion collisions at {radical}s{sub NN} {approx} 200 GeV, the azimuthal emission anisotropy of hadrons with low and intermediate transverse momentum (p{sub T} {approx}< 4 GeV/c) displays an intriguing scaling. In particular, the baryon (meson) emission patterns are consistent with a scenario in which a bulk medium of flowing quarks coalesces into three-quark (two-quark) 'bags.' While a full understanding of this number-of-constituent-quark (NCQ) scaling remains elusive…

Can baryon stopping explain the breakdown of constituent quark scaling and proposed signals of chiral magnetic waves at RHIC
Azimuthal emission spectra of various hadron species in ultra-relativistic heavy ion collisions at ? 200 GeV exhibit a curious hierarchy at intermediate pt (? 2 ? 3 GeV). Rather than being ordered by
Centrality and Transverse Momentum Dependence of Elliptic Flow of Multistrange Hadrons and ϕ Meson in Au+Au Collisions at √[sNN]=200  GeV.
It is observed that the transverse momentum dependence of ϕ and Ω v2 is similar to that of π and p, respectively, which may indicate that the heavier strange quark flows as strongly as the lighter up and down quarks.
Experimental studies of the quantum chromodynamics phase diagram at the STAR experiment
We review the STAR experiment’s results to date from the Beam Energy Scan (BES) at Brookhaven’s Relativistic Heavy Ion Collider, and outline future plans and prospects in this area. BES Phase-I is
Probing the QCD phase boundary with elliptic flow in relativistic heavy ion collisions at STAR
We present measurement of elliptic flow, v2, for charged and identified particles at midrapidity in Au+Au collisions at $\sqrt {s_{NN} } $ = 7.7–39 GeV. We compare the inclusive charged hadron v2 to
Probe the partonic/hadronic matter with elliptic flow in STAR Beam Energy Scan
One of the goal of RHIC Beam Energy Scan program is to search for the phase transition boundary between partonic and hadronic matters. Azimuthal anisotropy is expected to be sensitive to the degree
Influence of electromagnetic fields in proton-nucleus collisions at relativistic energy
We study proton-gold collisions at RHIC energy $\sqrt{s_{NN}}=200$ GeV within the Parton-Hadron-String Dynamics (PHSD) off-shell transport approach, investigating the influence of the intense
Highlights from the STAR experiment
We present an overview of the recent results obtained by the STAR Collaboration at RHIC.We report the beam energy dependence of directed flow of strange particles. These results support the
