Transverse single-spin asymmetry of forward $η$ mesons in $p^{↑} + p$ collisions at $s = 200$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +380

Utilizing the 2012 transversely polarized proton data from the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, the forward $η$ -meson transverse single-spin asymm…

Cross sections of $η$ 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 $η$ -meson cross sections from $p$ $+$ $p$ collisions at $s = 500$ and $510$ ~GeV, respectively. We also report th…

Multiplicity dependent $J / ψ$ and $ψ (2 S)$ production at forward and backward rapidity in $p$ $+$ $p$ collisions at $s = 200$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +298

The $J / ψ$ and $ψ (2 S)$ charmonium states, composed of $c c ˉ$ quark pairs and known since the 1970s, are widely believed to serve as ideal probes to test quantum chromodynamics i…

Transverse single-spin asymmetry of charged hadrons at forward and backward rapidity in polarized $p$ + $p$ , $p$ +Al, and $p$ +Au collisions at $s_{N N} = 200$ GeV}

N. J. Abdulameer, U. Acharya, C. Aidala +319

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 polarize…
