Balance functions have been measured for charged-particle pairs, identified charged-pion pairs, and identified charged-kaon pairs in $\mathrm{Au}+\mathrm{Au}$, $d+\mathrm{Au}$, and $p+p$ collisions at $\sqrt{{s}_{\mathit{NN}}}=200$ GeV at the Relativistic Heavy Ion Collider using the STAR detector. These balance functions are presented in terms of …

We report on a measurement of the $\ensuremath{\Upsilon}(1\mathrm{S}+2\mathrm{S}+3\mathrm{S})\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}$ cross section at midrapidity in $p+p$ collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$. We find the cross section to be $114\ifmmode\pm\else\textpm\fi{}38(\mathrm{stat}+\mathrm{\text{fit}}{)}_{\ensuremath{-}24}^{+23}(\mathrm{syst})\text{ }\text{ }\mathrm{pb}$. Perturbative QCD calculations at next-to-leading order in the color evaporation model are in …

We report a measurement of high-${p}_{T}$ inclusive ${\ensuremath{\pi}}^{0}$, $\ensuremath{\eta}$, and direct photon production in $p+p$ and $d+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200 \mathrm{GeV}$ at midrapidity ($0<\ensuremath{\eta}<1$). Photons from the decay ${\ensuremath{\pi}}^{0}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$ were detected in the barrel electromagnetic calorimeter of the STAR experiment at the …

We present the results of an elliptic flow, ${v}_{2}$, analysis of $\mathrm{Cu}+\mathrm{Cu}$ collisions recorded with the solenoidal tracker detector (STAR) at the BNL Relativistic Heavy Ion Collider at $\sqrt{{s}_{\mathit{NN}}}=62.4$ and $200$ GeV. Elliptic flow as a function of transverse momentum, ${v}_{2}$(${p}_{T}$), is …

We present the first large-acceptance measurement of event-wise mean transverse momentum $\ensuremath{\langle}{p}_{t}\ensuremath{\rangle}$ fluctuations for Au-Au collisions at nucleon-nucleon center-of-momentum collision energy $\sqrt{{s}_{\mathit{NN}}}$ = 130 GeV. The observed nonstatistical $\ensuremath{\langle}{p}_{t}\ensuremath{\rangle}$ fluctuations substantially exceed in magnitude fluctuations expected from the finite number of particles …
