Abstract
High transverse momentum (p T ) production of pions and photons in proton-proton and proton-antiproton interactions are studied within the QCD framework and compared with the presently available experimental data. Scaling violation effects are included, and shown to be important at largep T . Predictions are made for the γ/π0 ratio at collider energies. The possibility of extricating the gluon distribution function from the invariant cross section data for the process\(\bar p\)+p→γ+X is suggested.
