Low-mass vector-meson production at forward rapidity in p+p and Au+Au collisions at √sNN=200 GeV

Popis výsledku v původním jazyce

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured low-mass vector-meson (ω+ρ and ϕ) production through the dimuon decay channel at forward rapidity (1.2<|y|<2.2) in p+p and Au+Au collisions at √sNN=200 GeV. The low-mass vector-meson yield and nuclear-modification factor were measured as a function of the average number of participating nucleons, 〈Npart〉, and the transverse momentum pT. These results were compared with those obtained via the kaon decay channel in a similar pT range at midrapidity. The nuclear-modification factors in both rapidity regions are consistent within the uncertainties. A comparison of the ω+ρ and J/ψ mesons reveals that the light and heavy flavors are consistently suppressed across both pT and 〈Npart〉. In contrast, the ϕ meson displays a nuclear-modification factor consistent with unity, suggesting strangeness enhancement in the medium formed.
