Study of multiparticle production by gluon dominance model (Part II)

TL;DR

This paper advances the gluon dominance model to better describe multiparticle production in proton-proton and proton-antiproton collisions, explaining experimental data and proposing a soft photon production mechanism as a hadronization signature.

Contribution

It introduces modifications to the gluon dominance model by including intermediate quark topology and proposes a soft photon production mechanism linked to hadronization processes.

Findings

Parameters explain RHIC data on multiplicity distributions.

Modified model describes behavior of second correlative moment.

Soft photon excess estimates hadronization emission region size.

Abstract

The gluon dominance model presents a description of multiparticle production in proton-proton collisions and proton-antiproton annihilation. The collective behavior of secondary particles in $pp$-interactions at 70 GeV/c and higher is studied in the project {\bf "Thermalization"}. The obtained neutral and charged multiplicity distribution parameters explain some RHIC-data. The gluon dominance model is modified by the inclusion of intermediate quark topology for the multiplicity distribution description in the pure $p\bar p$-annihilation at few tens GeV/c and explains behavior of the second correlative moment. This article proposes a mechanism of the soft photon production as a sign of hadronization. Excess of soft photons allows one to estimate the emission region size.
