Universality in hadron production in electron-positron, lepton-hadron and hadron-hadron reactions

TL;DR

This paper discusses the universality of hadron production mechanisms across different high-energy reactions, emphasizing that differences arise mainly from initial parton flavors rather than the fundamental process.

Contribution

It analyzes recent data to support the universality hypothesis in hadron formation across e+e-, lepton-hadron, and hadron-hadron reactions.

Findings

Supports universality in hadron production mechanisms

Differences in final particle composition are due to initial parton flavors

Recent data aligns with the universality concept

Abstract

According to the concept of universality in hadron production, the basic mechanisms of hadron formation are the same in all high-energy e+e-, lh and hh reactions, with differences in the composition of final-state particle types being due only to differences in initial parton flavours and configurations. This concept is discussed in the light of recent data and phenomenology.
