DESCRIPTION
Introduction Production of prompt photon –Quark - gluon scattering is dominant sub-process at pp collision in √ s = 62.4 GeV The related experiment –PHENIX √ s = 200 GeV –R806, AFS, CCOR and CMOR using ISR collider at √ s = 63 GeV in CERN Test the applicability of perturbative QCD (pQCD) –Comparing the cross section of measurement to the one of pQCD calculation pQCD calculation in qg scattering : –Once the applicable range of pQCD is determined, the framework of pQCD can be used to calculate other quantities of interest, in particular A LL prompt photon proton gluon quark proton q(x), g(x) : PDF for quark, gluon : sub-process cross section
