Abstract
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}).
Highlights
The φð1020Þ-vector-meson production in p þ p collisions was intensively studied by various experiments at different colliding energies and in different rapidity ranges [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18]
We report the φ-meson-pproffidffi uction cross section measured in p þ p collisions at s 1⁄4 510 GeV
The measured pT-differential cross section is compared to various model predictions based on PYTHIA6, PYTHIA8, PHOJET, AMPT, EPOS3, and EPOS-LHC generators
Summary
The φð1020Þ-vector-meson production in p þ p collisions was intensively studied by various experiments at different colliding energies and in different rapidity ranges [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18]. It is the lightest bound state of s and squarks and is considered a good probe to study strangeness production in p þ p collisions.
