Measurement of ϕ -meson production at forward rapidity in p + p collisions at s = 510 GeV and its energy dependence from s = 200 GeV to 7 TeV

A. Adare, C. Aidala, N. N. Ajitanand, Y. Akiba et autres

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section of $\ensuremath{\phi}(1020)$-meson production at forward rapidity in $p+p$ collisions at $\sqrt{s}=510\text{ }\text{ }\mathrm{GeV}$ via the dimuon decay channel. The partial cross section in the rapidity and ${p}_{T}$ …

Angular decay coefficients of J/ψ mesons at forward rapidity from p+p collisions at s=510 GeV

A. Adare, C. Aidala, N. N. Ajitanand, Y. Akiba et autres

We report the first measurement of the full angular distribution for inclusive $J/\ensuremath{\psi}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ decays in $p+p$ collisions at $\sqrt{s}=510\text{ }\text{ }\mathrm{GeV}$. The measurements are made for $J/\ensuremath{\psi}$ transverse momentum $2<{p}_{T}<10\text{ }\text{ }\mathrm{GeV}/c$ and rapidity $1.2<y<2.2$ in the Helicity, Collins-Soper, and Gottfried-Jackson reference …

Measurements of B→J/ψ at forward rapidity in p+p collisions at s=510 GeV

C. Aidala, N. N. Ajitanand, Y. Akiba, R. Akimoto et autres

We report the first measurement of the fraction of $J/\ensuremath{\psi}$ mesons coming from $B$-meson decay (${F}_{B\ensuremath{\rightarrow}J/\ensuremath{\psi}}$) in $p+p$ collisions at $\sqrt{s}=510\text{ }\text{ }\mathrm{GeV}$. The measurement is performed using the forward silicon vertex detector and central vertex detector at PHENIX, which provide precise …

Azimuthal anisotropy of π0 and η mesons in Au + Au collisions at sNN=200 GeV

The azimuthal anisotropy coefficients ${v}_{2}$ and ${v}_{4}$ of ${\ensuremath{\pi}}^{0}$ and $\ensuremath{\eta}$ mesons are measured in Au + Au collisions at $\sqrt{{s}_{\mathit{\text{NN}}}}=200$ GeV as a function of transverse momentum ${p}_{T}$ (1--14 GeV/$c$) and centrality. The extracted ${v}_{2}$ coefficients are found to be consistent …

Measurements of the anisotropy parameter ${v}_{2}$ of identified hadrons (pions, kaons, and protons) as a function of centrality, transverse momentum ${p}_{T}$, and transverse kinetic energy KE${}_{T}$ at midrapidity ($|\ensuremath{\eta}|<0.35$) in Au + Au collisions at $\sqrt{{s}_{NN}}=200$ GeV are presented.

Cross Section and Parity-Violating Spin Asymmetries of W± Boson Production in Polarized p+p Collisions at s=500 GeV

Large parity-violating longitudinal single-spin asymmetries ${A}_{L}^{{e}^{+}}=\ensuremath{-}{0.86}_{\ensuremath{-}0.14}^{+0.30}$ and ${A}_{L}^{{e}^{\ensuremath{-}}}={0.88}_{\ensuremath{-}0.71}^{+0.12}$ are observed for inclusive high transverse momentum electrons and positrons in polarized $p+p$ collisions at a center-of-mass energy of $\sqrt{s}=500\text{ }\text{ }\mathrm{GeV}$ with the PHENIX detector at RHIC. These ${e}^{\ifmmode\pm\else\textpm\fi{}}$ come mainly from the …

Cross section and double helicity asymmetry for η mesons and their comparison to π0 production in p+p collisions at s=200 GeV

A. Adare, S. Afanasiev, C. Aidala, N. N. Ajitanand et autres

Measurements of double-helicity asymmetries in inclusive hadron production in polarized $p+p$ collisions are sensitive to helicity-dependent parton distribution functions, in particular, to the gluon helicity distribution, $\ensuremath{\Delta}g$. This study focuses on the extraction of the double-helicity asymmetry in $\ensuremath{\eta}$ production ($\stackrel{\ensuremath{\rightarrow}}{p}+\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\rightarrow}\ensuremath{\eta}+X$), the …
