Particle production in proton-proton collisions

TL;DR

This paper analyzes particle production mechanisms in proton-proton collisions across various energies, focusing on how production processes differ for pions and heavier particles like keons and lambda hyperons.

Contribution

It provides a comprehensive study of particle production mechanisms over a wide energy range and compares the production of pions with heavier particles in proton-proton collisions.

Findings

Particle production mechanisms vary with energy.

Heavier particles may be produced via different mechanisms than pions.

The study offers insights into the energy dependence of particle production.

Abstract

In this work, we present a study of particle production in proton-proton collisions using data that are collected from many experiments of relative wide range of reaction energies. These data include production of pions and heavier particles; like keons and lambda hyperons. Proton-proton collision is a simple system to investigate and to be considered a starting point that guides to more complicated processes of production in the proton-nucleus and the nucleus-nucleus collisions. In this paper, we are interested in the mechanisms that describe the process of particle production over a wide range of interaction energy, and how the physics of production changes with changing energy. Besides, this work may raise a question: are heavier particles than pions produced via the same mechanism(s) of producing pions, or these are created differently, being different in masses and other physical properties?
