Real photons produced from photoproduction in $pp$ collisions

TL;DR

This paper calculates real photon production from photoproduction in high-energy proton-proton collisions, using the Weizs"acker-Williams approximation, and finds good agreement with experimental data, especially at high transverse momentum.

Contribution

It introduces a detailed calculation of photoproduction of real photons in $pp$ collisions using the Weizs"acker-Williams approximation, aligning theory with experimental results.

Findings

Numerical results match RHIC and LHC data.

Photoproduction modification is significant at high transverse momentum.

The approach effectively describes real photon production in $pp$ collisions.

Abstract

We calculate the production of real photons originating from the photoproduction in relativistic $pp$ collisions. The Weizs$\ddot{\mathrm{a}}$cker-Williams approximation in the photoproduction is considered. Numerical results agree with the experimental data from Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC). We find that the modification of the photoproduction is more prominent in large transverse momentum region.
