Role of quarks in hadroproduction in high energy collisions

TL;DR

This paper proposes a qualitative model for hadroproduction in high energy collisions, dividing it into 'thermal' and 'hard' components, and analyzes experimental data to support the model's predictions about particle spectra.

Contribution

It introduces a new qualitative model distinguishing 'thermal' and 'hard' components in hadroproduction and compares it with experimental data.

Findings

Pseudorapidity distributions match the model's expectations.

Differences observed between inclusive and diffractive events.

Absence of 'thermal' component in diffractive events.

Abstract

Qualitative model for hadroproduction in high energy collisions considering two components ("thermal" and "hard") to hadroproduction is proposed. Inclusive pseudorapidity distributions, $d\sigma/d\eta$, and transverse momentum spectra, $d^2\sigma/(d\eta dp_T^2)$, measured by different collaborations are considered in terms of this model. The shapes of the pseudorapidity distributions agree with that one can expect from the qualitative picture introduced. Finally, the differences between charged particle spectra produced in inclusive and diffractive events are discussed and the absence of the "thermal" component in the latter is observed.
