Kinetic description of hadron-hadron collisions

TL;DR

This paper introduces a transport model for proton-proton collisions based on parton liberation and coalescence, suggesting the possible formation of quark-gluon plasma in high-energy pp collisions.

Contribution

It presents a novel kinetic model treating hadrons as bags of partons and predicts QGP formation in high-energy proton-proton collisions.

Findings

Model agrees well with existing data

Predicts QGP formation at high energies

Provides insights into hadronization process

Abstract

A transport model based on the mean free path approach to describe pp collisions is proposed. We assume that hadrons can be treated as bags of partons similarly to the MIT bag model. When the energy density in the collision is higher than a critical value, the bags break and partons are liberated. The partons expand and can make coalescence to form new hadrons. The results obtained compare very well with available data and some prediction for higher energies collisions are discussed. Based on the model we suggest that a QGP could already be formed in the pp collisions at high energies.
