We present measurements of π− and π+ elliptic flow, v2, at midrapidity in Au+Au collisions √sNN=200, 62.4, 39, 27, 19.6, 11.5, 7.7 GeV, as a function event-by-event charge asymmetry, Ach, based on data from the STAR experiment RHIC. find that (π+) flow linearly increases (decreases) with asymmetry for most centrality bins √sNN=27 GeV higher. At √sNN=200 slope difference v2 between Ach exhibits dependence, which is qualitatively similar to calculations incorporate chiral magnetic wave effect....
Collisions between prolate uranium nuclei are used to study how particle production and azimuthal anisotropies depend on initial geometry in heavy-ion collisions. We report the two- four-particle cumulants, $v_2\{2\}$ $v_2\{4\}$, for charged hadrons from U+U collisions at $\sqrt{s_{\rm NN}}$ = 193 GeV Au+Au 200 GeV. Nearly fully overlapping selected based amount of energy deposited by spectators STAR Zero Degree Calorimeters (ZDCs). Within this sample, observed dependence multiplicity...
Dihadron angular correlations in d+Au collisions at sNN=200GeV are reported as a function of the measured zero-degree calorimeter neutral energy and forward charged hadron multiplicity Au-beam direction. A finite correlated yield is observed large relative pseudorapidity (Δη) on near side (i.e. azimuth Δϕ∼0). This Δη appears to scale with dominant, primarily jet-related, away-side (Δϕ∼π) yield. The Fourier coefficients Δϕ correlation, Vn=〈cosnΔϕ〉, have strong dependence. In addition, it...
We report the triton ($t$) production in mid-rapidity ($|y| <$ 0.5) Au+Au collisions at $\sqrt{s_\mathrm{NN}}$= 7.7--200 GeV measured by STAR experiment from first phase of beam energy scan Relativistic Heavy Ion Collider (RHIC). The nuclear compound yield ratio ($\mathrm{N}_t \times \mathrm{N}_p/\mathrm{N}_d^2$), which is predicted to be sensitive fluctuation local neutron density, observed decrease monotonically with increasing charged-particle multiplicity ($dN_{ch}/d\eta$) and follows a...
We report the beam energy and collision centrality dependence of fifth sixth order cumulants (C5, C6) factorial (κ5, κ6) net-proton proton number distributions, from center-of-mass (√sNN) 3 GeV to 200 Au+Au collisions at RHIC. Cumulant ratios (taken as proxy for net-baryon) distributions generally follow hierarchy expected QCD thermodynamics, except case GeV. The measured values C6/C2 0%–40% show progressively negative trend with decreasing energy, while it is positive lowest studied. These...

We present results from a harmonic decomposition of two-particle azimuthal correlations measured with the STAR detector in Au+Au collisions for energies ranging $\sqrt{s_{NN}}=7.7$ GeV to 200 GeV. The third $v_3^2\{2\}=\langle \cos3(\phi_1-\phi_2)\rangle$, where $\phi_1-\phi_2$ is angular difference azimuth, studied as function pseudorapidity between particle pairs $\Delta\eta = \eta_1-\eta_2$. Non-zero {\vthree} directly related previously observed large-$\Delta\eta$ narrow-$\Delta\phi$...

The charged-hadron per-trigger yields mid-rapidity from compared to quantify suppression collisions. away-side associated-particle per $γ_{dir}$ is independent transverse momentum particle ($p_{T}^{\mathrm{trig}}$), whereas smaller low associated...
We report on measurements of sequential ϒ suppression in Au+Au collisions at sqrt[s_{NN}]=200 GeV with the STAR detector Relativistic Heavy Ion Collider (RHIC) through both dielectron and dimuon decay channels.

A decisive experimental test of the Chiral Magnetic Effect (CME) is considered one major scientific goals at Relativistic Heavy-Ion Collider (RHIC) towards understanding nontrivial topological fluctuations Quantum Chromodynamics vacuum. In heavy-ion collisions, CME expected to result in a charge separation phenomenon across reaction plane, whose strength could be strongly energy dependent. The previous searches have been focused on top RHIC collisions. this Letter, we present low search for...

Dihadron correlations are analyzed in sNN=200GeV d+Au collisions classified by forward charged particle multiplicity and zero-degree neutral energy the Au-beam direction. It is found that jetlike correlated yield increases with event multiplicity. After taking into account this dependence, non-jet contribution on away side minimal, leaving little room for a back-to-back ridge these collisions.
A search for the quantum chromodynamics (QCD) critical point was performed by STAR experiment at BNL Relativistic Heavy Ion Collider, using dynamical fluctuations of unlike particle pairs. ion collisions were studied over a large range collision energies with homogeneous acceptance and excellent identification, covering significant in QCD phase diagram where may be located. Dynamical $K\ensuremath{\pi}$, $p\ensuremath{\pi}$, $Kp$ as measured central 0--5% Au + from center-of-mass...
Balance functions have been measured in terms of relative pseudorapidity (Δη) for charged particle pairs at the BNL Relativistic Heavy Ion Collider from Au + collisions √sNN=7.7GeV to 200 GeV using STAR detector. These results are compared with balance CERN Large Hadron Pb √sNN=2.76TeV by ALICE Collaboration. The width function decreases as become more central and beam energy is increased. In contrast, widths calculated shuffled events show little dependence on centrality or larger than...
