Modeling photon radiation in soft hadronic collisions

TL;DR

This paper models photon radiation in soft hadronic collisions using higher Fock states and the Quark-Gluon String Model, achieving good agreement with experimental data across various photon transverse momenta.

Contribution

It introduces a novel approach combining Fock state descriptions with the Quark-Gluon String Model and color-dipole phenomenology for photon radiation in soft collisions.

Findings

Calculated photon spectra agree with experimental data

The model accurately describes photon production across a wide transverse momentum range

Provides a unified framework for soft hadronic collision analysis

Abstract

Soft hadronic collisions with multiple production of (anti)quarks accompanied with soft photon radiation are described in terms of higher Fock states of the colliding hadrons, which contain a photon component as well. The Fock state distribution functions are shaped with the Quark-Gluon String Model. Photon radiation by quarks is described within the color-dipole phenomenology. The results of calculations are in a good accord with available data in a wide range of transverse momenta of the photons.
