Sažetak (engleski)
The PHENIX experiment at RHIC has measured the centrality dependence of the direct photon yield from Au + Au collisions at √sNN = 200 GeV down to p_T = 0.4 GeV/c. Photons are detected via photon conversions to e+e− pairs and an improved technique is applied that minimizes the systematic uncertainties that usually limit direct photon measurements, in particular at low p_T . We find an excess of direct photons above the N_coll-scaled yield measured in p + p collisions. This excess yield is well described by an exponential distribution with an inverse slope of about 240 MeV/c in the p_T range 0.6–2.0 GeV/c. While the shape of the pT distribution is independent of centrality within the experimental uncertainties, the yield increases rapidly with increasing centrality, scaling approximately with N^α_part, where α = 1.38 ± 0.03(stat) ± 0.07(syst).
