The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section of $phi$(1020)-meson production at forward rapidity in $p$$+$$p$ collisions at $sqrt{s}=$510 GeV via the dimuon decay channel. The partial cross section in the rapidity and $p_T$ ranges $1.2<|y|<2.2$ and $2<p_T<7$ GeV/$c$ is $sigma_phi=[2.28 pm 0.09,{rm (stat)} pm 0.14,{rm (syst)} pm 0.27, {rm (norm)}] times 10^{-2}$~mb. The energy dependence of $sigma_phi$ ($1.2<|y|<2.2, ; 2<p_T<5$ GeV/$c$) is studied using the PHENIX measurements at $sqrt{s}=$200 and 510 GeV and the Large-Hadron-Collider measurements at $sqrt{s}=$2.76 and 7 TeV. The experimental results are compared to various event generator predictions ({sc pythia6, pythia8, phojet, ampt, epos3,} and {sc epos-lhc}).
The cross section of bottom quark-antiquark ($bbar{b}$) production in $p$+$p$ collisions at $sqrt{s}=510$ GeV is measured with the PHENIX detector at the Relativistic Heavy Ion Collider. The results are based on the yield of high mass, like-sign muon
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured low mass vector meson, $omega$, $rho$, and $phi$, production through the dimuon decay channel at forward rapidity ($1.2<|y|<2.2$) in $p$$+$$p$ collisions at $sqrt{s}=200$ GeV.
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section, mean transverse momentum, mean transverse momentum squared of inclusive $J/psi$ and cross-section ratio of $psi(2S)$ to $J/psi$ at forward rapid
We report the first measurement of the fraction of $J/psi$ mesons coming from $B$-meson decay ($F_{B{rightarrow}J/psi}$) in $p$+$p$ collisions at $sqrt{s}=$ 510 GeV. The measurement is performed using the forward silicon vertex detector and central v
We report the first measurement of the full angular distribution for inclusive $J/psirightarrowmu^{+}mu^{-}$ decays in $p$$+$$p$ collisions at $sqrt{s}=510$ GeV. The measurements are made for $J/psi$ transverse momentum $2<p_{T}<10$ GeV/$c$ and rapid
