Abstract

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section of φ(1020)-meson production at forward rapidity in p+p collisions at s=510 GeV via the dimuon decay channel. The partial cross section in the rapidity and pT ranges 1.2<|y|<2.2 and 2<pT<7 GeV/c is σφ=[2.28±0.09(stat)±0.14(syst)±0.27(norm)]×10-2 mb. The energy dependence of σφ (1.2<|y|<2.2,2<pT<5 GeV/c) is studied using the PHENIX measurements at s=200 and 510 GeV and the Large Hadron Collider measurements at s=2.76 and 7 TeV. The experimental results are compared to various event generator predictions (pythia6, pythia8, phojet, ampt, epos3, and epos-lhc). © 2018 authors. Published by the American Physical Society.
