We measured direct photons for ${p}_{T}<5\phantom{\rule{3.33333pt}{0ex}}\mathrm{GeV}/c$ in minimum bias and 0%--40% most-central events at midrapidity for $\mathrm{Cu}+\mathrm{Cu}$ collisions at $\sqrt{{s}_{{}_{NN}}}=200\phantom{\rule{4pt}{0ex}}\mathrm{GeV}$. The ${e}^{+}{e}^{\ensuremath{-}}$ contribution from quasireal direct virtual photons has been determined as an excess over the known hadronic contributions in the ${e}^{+}{e}^{\ensuremath{-}}$ …

Measurements of the fractional momentum loss $({S}_{\mathrm{loss}}\ensuremath{\equiv}\ensuremath{\delta}{p}_{T}/{p}_{T})$ of high-transverse-momentum-identified hadrons in heavy-ion collisions are presented. Using ${\ensuremath{\pi}}^{0}$ in $\mathrm{Au}+\mathrm{Au}$ and $\mathrm{Cu}+\mathrm{Cu}$ collisions at $\sqrt{{s}_{{}_{NN}}}=62.4$ and 200 GeV measured by the PHENIX experiment at the Relativistic Heavy Ion Collider and and charged hadrons …

The production of ${e}^{+}{e}^{\ensuremath{-}}$ pairs for ${m}_{{e}^{+}{e}^{\ensuremath{-}}}<0.3\text{ }\text{ }\mathrm{GeV}/{c}^{2}$ and $1<{p}_{T}<5\text{ }\text{ }\mathrm{GeV}/c$ is measured in $p+p$ and $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. An enhanced yield above hadronic sources is observed. Treating the excess as photon internal conversions, the invariant yield …
