We report the observation at the Relativistic Heavy Ion Collider of suppression of back-to-back correlations in the direct photon+jet channel in $\mathrm{Au}+\mathrm{Au}$ relative to $p+p$ collisions. Two-particle correlations of direct photon triggers with associated hadrons are obtained by statistical subtraction of the …

The momentum distribution of electrons from semileptonic decays of charm and bottom quarks for midrapidity $|y|<0.35$ in $p+p$ collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$ is measured by the PHENIX experiment at the Relativistic Heavy Ion Collider over the transverse momentum range $2<{p}_{T}<7\text{ }\text{ …

The double helicity asymmetry in neutral pion production for ${p}_{T}=1$ to $12\text{ }\text{ }\mathrm{GeV}/c$ was measured with the PHENIX experiment to access the gluon-spin contribution, $\ensuremath{\Delta}G$, to the proton spin. Measured asymmetries are consistent with zero, and at a theory scale of …
