Description
The prompt photon production in p-p collisions at high energies is studied. Double-spin asymmetry of the process is calculated by using Monte Carlo code SPHINX. A possibility to discriminate the spin-dependent gluon distributions and to determine sign of Delta G is discussed. Detailed study of expected background, such as pi0 production and decay, is given. The predictions for the longitudinal asymmetry of the prompt photons and pi0-meson production in the p-p collisions at RHIC energies have been made.
