Reported here are transverse single-spin asymmetries (${A}_{N}$) in the production of charged hadrons as a function of transverse momentum (${p}_{T}$) and Feynman-$x$ (${x}_{F}$) in polarized ${p}^{\ensuremath{\uparrow}}+p$, ${p}^{\ensuremath{\uparrow}}+\mathrm{Al}$, and ${p}^{\ensuremath{\uparrow}}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. The measurements have been performed at forward and …

We present measurements of azimuthal correlations of charged hadron pairs in $\sqrt{{s}_{\mathit{NN}}}=200$ GeV $\mathrm{Au}+\mathrm{Au}$ collisions for the trigger and associated particle transverse-momentum ranges of $1<{p}_{T}^{t}<10\phantom{\rule{4pt}{0ex}}\mathrm{GeV}/c$ and $0.5<{p}_{T}^{a}<10\phantom{\rule{4pt}{0ex}}\mathrm{GeV}/c$. After subtraction of an underlying event using a model that includes higher-order azimuthal anisotropy ${v}_{2}, …

The PHENIX collaboration has measured high-${p}_{T}$ dihadron correlations in $p+p, p+\mathrm{Al}$, and $p+\mathrm{Au}$ collisions at $\sqrt{{s}_{{}_{NN}}}=200$ GeV. The correlations arise from inter- and intrajet correlations and thus have sensitivity to nonperturbative effects in both the initial and final states. The distributions of …

The fraction of $J/\ensuremath{\psi}$ mesons which come from $B$-meson decay, ${\mathrm{F}}_{B\ensuremath{\rightarrow}J/\ensuremath{\psi}}$, is measured for $\mathrm{J}/\ensuremath{\psi}$ rapidity $1.2<|y|<2.2$ and ${p}_{T}>0$ in $p+p$ and Cu+Au collisions at $\sqrt{{s}_{{}_{NN}}}$ = 200 GeV with the PHENIX detector. The extracted fraction is ${\mathrm{F}}_{B\ensuremath{\rightarrow}J/\ensuremath{\psi}}=0.025\ifmmode\pm\else\textpm\fi{}0.006$ (stat) $\ifmmode\pm\else\textpm\fi{}$ 0.010(syst) for …

We report a measurement of ${e}^{+}{e}^{\ensuremath{-}}$ pairs from semileptonic heavy-flavor decays in $p+p$ collisions at $\sqrt{{s}_{{}_{\mathit{\text{NN}}}}}=200$ GeV. The ${e}^{+}{e}^{\ensuremath{-}}$ pair yield from $b\overline{b}$ and $c\overline{c}$ is separated by exploiting a double differential fit done simultaneously in dielectron invariant mass and ${p}_{T}$. We …

Jet production rates are measured in p+p and d+Au collisions at sqrt[s_{NN}]=200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the R=0.3 anti-k_{t} algorithm from energy deposits in the electromagnetic calorimeter and …

The energy dependence of the single-transverse-spin asymmetry, ${A}_{N}$, and the cross section for neutron production at very forward angles were measured in the PHENIX experiment at the Relativistic Heavy Ion Collider for polarized $p+p$ collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$. The neutrons were …

Transverse momentum spectra of electrons (${p}_{T}^{e}$) from semileptonic weak decays of heavy-flavor mesons in the range of $0.3<{p}_{T}^{e}<9.0$ GeV/$c$ have been measured at midrapidity ($|y|<0.35$) by the PHENIX experiment at the Relativistic Heavy Ion Collider in $p+p$ and $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{\mathrm{NN}}}=200$ …

New measurements by the PHENIX experiment at the Relativistic Heavy Ion Collider for $\ensuremath{\eta}$ production at midrapidity as a function of transverse momentum (${p}_{T}$) and collision centrality in $\sqrt{{s}_{\mathit{NN}}}=200$ GeV $\mathrm{Au}+\mathrm{Au}$ and $p+p$ collisions are presented. They indicate nuclear modification factors (${R}_{\mathrm{AA}}$) …
