Özet
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.
