Strange hadrons are an excellent probe for identifying the phase boundary and onset of deconfinement in the QCD phase diagram. The STAR Collaboration has performed precision measurements of the abundances and transverse-momentum distributions for 8 species of strange mesons and baryons, as …

We report the first measurement of rapidity-odd directed flow (${v}_{1}$) for ${D}^{0}$ and $\overline{{D}^{0}}$ mesons at midrapidity ($|y|<0.8$) in $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{\mathrm{NN}}}=200\text{ }\text{ }\mathrm{GeV}$ using the STAR detector at the Relativistic Heavy Ion Collider. In 10--80% $\mathrm{Au}+\mathrm{Au}$ collisions, the slope of …

We report on the first measurements of $J/\ensuremath{\psi}$ production at very low transverse momentum (${p}_{T}<0.2\text{ }\text{ }\mathrm{GeV}/c$) in hadronic $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$ and $\mathrm{U}+\mathrm{U}$ collisions at $\sqrt{{s}_{NN}}=193\text{ }\text{ }\mathrm{GeV}$. Remarkably, the inferred nuclear modification factor of $J/\ensuremath{\psi}$ at midrapidity …

J / ψ suppression has long been considered a sensitive signature of the formation of the Quark-Gluon Plasma (QGP) in relativistic heavy-ion collisions. In this letter, we present the first measurement of inclusive J / ψ production at mid-rapidity through the dimuon …

We report the first measurement of the inclusive jet and the dijet longitudinal double-spin asymmetries, ${A}_{LL}$, at midrapidity in polarized $pp$ collisions at a center-of-mass energy $\sqrt{s}=510\text{ }\text{ }\mathrm{GeV}$. The inclusive jet ${A}_{LL}$ measurement is sensitive to the gluon helicity distribution down …

The first (${v}_{1}^{\mathrm{fluc}}$), second (${v}_{2}$), and third (${v}_{3}$) harmonic coefficients of the azimuthal particle distribution at midrapidity are extracted for charged hadrons and studied as a function of transverse momentum (${p}_{T}$) and mean charged particle multiplicity density $⟨{N}_{\mathrm{ch}}⟩$ in $U+U$ ($\sqrt{{s}_{NN}}=193\text{ }\text{ …

We report a new measurement of ${D}^{0}$-meson production at mid-rapidity $(|y|<1)$ in Au + Au collisions at $\sqrt{{s}_{\mathrm{NN}}}=200\phantom{\rule{0.16em}{0ex}}\mathrm{GeV}$ utilizing the heavy flavor tracker, a high resolution silicon detector at the STAR experiment. Invariant yields of ${D}^{0}$ mesons with transverse momentum ${p}_{T}\ensuremath{\lesssim}9\phantom{\rule{0.16em}{0ex}}\mathrm{GeV}/c$ are …

In this erratum we report changes on the $D^0$ $p_T$ spectra and nuclear modification factor ($R_{AA}$) in Au+Au collisions at $\sqrt{s_{_{\mathrm{NN}}}}$ = 200 GeV by fixing the errors in the efficiency and selection criteria that affected the Au+Au results. The p+p reference …
