Large Transverse Momentum Photon Generated in Relativistic Proton-Proton Collisions
Based on the perturbative quantum chromodynamics and parton model, the large transverse momentum photon generated in the relativistic proton-proton collisions is researched. In the perturbative quantum chromodynamics, the large transverse momentum photons are produced from Compton scattering, quark anti-quark annihilation, gluon quark lap, and photon fragmentation of scattering final state of partons. Theoretical calculation results explain the experimental data of photon generated from proton-proton collisions in different ergoregions.
