We analyze a class of stochastically stable quenched measures. We prove that stochastic stability is fully characterized by an infinite family of zero average polynomials in the covariance matrix entries.

Calculations of the nuclear modification factor, R dAu , for π 0 production in dAu collisions at √ s = 200 AGeV are presented. The applied pQCD-improved parton model incorporates intrinsic k T. Nuclear multiscattering and nuclear shadowing are considered in the Au nucleus. Theoretical results are displayed for midrapidity and high pseudo-rapidity (η), and compared to preliminary PHENIX and BRAH...
