Centrality dependence of direct photon production in root s(NN) = 200 GeV Au+Au collisions.

The first measurement of direct photons in Au+Au collisions at {radical}(s{sub NN})=200 GeV is presented. The direct photon signal is extracted as a function of the Au+Au collision centrality and compared to next-to-leading order perturbative quantum chromodynamics calculations. The direct photon yield is shown to scale with the number of nucleon-nucleon collisions for all centralities.
