POLARIZED DOUBLE PHOTON PRODUCTION IN QCD TO ORDER ALPHA(S)

We present a complete order alpha(s) analysis of the process pp-->gamm a gamma+X with polarized initial states, previously studied by us with leading order structure functions. We include in our calculation new sets of parton densities evolved in NLO QCD, such as those of Gehrmann and Stirling and of Gluck et al., which incorporate the new anomalous dimensions of Mertig and Van Neerven in the evolution equation. A det ailed phenomenological analysis is also given which includes the photo n isolation. Our results indicate that the asymmetries, although not v ery large, should be substantial enough at BNL RHIC energies to be mea surable in future planned experiments.
