Real Photons Produced from Photoproduction in pp Collisions

We calculate the production of real photons originating from the photoproduction in relativistic pp collisions. The Weizs?cker–Williams approximation in the photoproduction is considered. Numerical results agree with the experimental data from the Relativistic Heavy Ion Collider and the Large Hadron Collider. We find that the modification of the photoproduction is more prominent in large transverse momentum regions.
