We report on the measurement of $J/\ensuremath{\psi}$ production in the dielectron channel at midrapidity $(|y|<1)$ in $p+p$ and $d+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\phantom{\rule{4pt}{0ex}}\mathrm{GeV}$ from the STAR experiment at the Relativistic Heavy Ion Collider. The transverse momentum ${p}_{T}$ spectra in $p+p$ for ${p}_{T}<4\phantom{\rule{4pt}{0ex}}\mathrm{GeV}/c$ and …

The $J/\ensuremath{\psi}$ ${p}_{T}$ spectrum and nuclear modification factor (${R}_{\mathit{AA}}$) are reported for ${p}_{T}<5\phantom{\rule{4pt}{0ex}}\mathrm{GeV}/c$ and $|y|<1$ from 0% to 60% central $\mathrm{Au}+\mathrm{Au}$ and $\mathrm{Cu}+\mathrm{Cu}$ collisions at $\sqrt{{s}_{NN}}=200\phantom{\rule{4pt}{0ex}}\mathrm{GeV}$ at STAR. A significant suppression of ${p}_{T}$-integrated $J/\ensuremath{\psi}$ production is observed in central $\mathrm{Au}+\mathrm{Au}$ events. The …

A study is reported of the same- and opposite-sign charge-dependent azimuthal correlations with respect to the event plane in Au + Au collisions at $\sqrt{{s}_{{}_{NN}}}=200$ GeV. The charge multiplicity asymmetries between the up/down and left/right hemispheres relative to the event plane are …

STAR measurements of dihadron azimuthal correlations ($\ensuremath{\Delta}\ensuremath{\phi}$) are reported in midcentral (20--60%) Au + Au collisions at $\sqrt{{s}_{{}_{\mathit{NN}}}}=200$ GeV as a function of the trigger particle's azimuthal angle relative to the event plane, ${\ensuremath{\phi}}_{s}=|{\ensuremath{\phi}}_{t}\ensuremath{-}{\ensuremath{\psi}}_{\mathrm{EP}}|$. The elliptic (${v}_{2}$), triangular (${v}_{3}$), and quadratic (${v}_{4}$) …

Previous experimental results based on data ($\ensuremath{\sim}$$15\ifmmode\times\else\texttimes\fi{}{10}^{6}$ events) collected by the STAR detector at the BNL Relativistic Heavy Ion Collider suggest event-by-event charge-separation fluctuations perpendicular to the event plane in noncentral heavy-ion collisions. Here we present the correlator previously used split into …

We present measurements of three-dimensional correlation functions of like-sign, low-transverse-momentum kaon pairs from $\sqrt{{s}_{NN}}=200$ GeV $\mathrm{Au}+\mathrm{Au}$ collisions. A Cartesian surface-spherical harmonic decomposition technique was used to extract the kaon source function. The latter was found to have a three-dimensional Gaussian shape and …
