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 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 …

PHENIX has measured the electron–positron pair mass spectrum from 0 to 8 GeV / c 2 in p + p collisions at s = 200 GeV . The contributions from light meson decays to e + e − pairs have been determined …

Azimuthal angle ($\ensuremath{\Delta}\ensuremath{\phi}$) correlations are presented for charged hadrons from dijets for $0.4<{p}_{T}<10$ GeV/$c$ in Au+Au collisions at $\sqrt{{s}_{\mathrm{NN}}}=200$ GeV. With increasing ${p}_{T}$, the away-side distribution evolves from a broad and relatively flat shape to a concave shape, then to a convex …
