Measurement of isolated prompt photon production in $p$ + $p$ collisions at $s = 200$ GeV with the sPHENIX detector

sPHENIX Collaboration, M. I. Abdulhamid, U. Acharya +217

The differential cross section of isolated prompt photon production is measured as a function of photon transverse energy ( $E_{T}^{3}$ ) in proton--proton ( $p$ + $p$ ) collisio…

Measurements at forward rapidity of elliptic flow of charged hadrons and open-heavy-flavor muons in Au $+$ Au collisions at $s_{_{N N}} = 200$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +365

We present the first forward-rapidity measurements of elliptic anisotropy of open-heavy-flavor muons at the BNL Relativistic Heavy Ion Collider. The measurements are based on data…

Cross sections of $I^\cdot$ mesons in $p$ $+$ $p$ collisions at forward rapidity at $s = 500$ GeV and central rapidity at $s = 510$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +497

We present the first measurements of the forward and midrapidity $I^\cdot$ -meson cross sections from $p$ $+$ $p$ collisions at $s = 500$ and $510$ ~GeV, respectively. We also report t…
