Low-mass vector-meson production at forward rapidity in p plus p and Au plus 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 (omega + rho and phi) production through the dimuon decay channel at forward rapidity (1.2 &lt; |y| &lt; 2.2) in p + p and Au + Au collisions at root s(NN) = 200 GeV. The low-mass vector-meson yield and nuclear-modification factor were measured as a function of the average number of participating nucleons, &lt; N-part &gt;, and the transverse momentum p(T). These results were compared with those obtained via the kaon decay channel in a similar p(T) range at midrapidity. The nuclear-modification factors in both rapidity regions are consistent within the uncertainties. A comparison of the omega + rho and J/psi mesons reveals that the light and heavy flavors are consistently suppressed across both p(T) and &lt; N-part &gt;. In contrast, the phi meson displays a nuclear-modification factor consistent with unity, suggesting strangeness enhancement in the medium formed.
