A variation of the charged particle spectrum shape as function of rapidity in high energy pp collisions

TL;DR

This paper analyzes how the shape of charged particle spectra varies with rapidity in high-energy proton-proton collisions, proposing a simple model to explain the observed effects.

Contribution

It introduces a qualitative model for hadroproduction that accounts for the variation of spectra shape with pseudorapidity in pp collisions.

Findings

Spectra shape varies with pseudorapidity.

A simple model describes the observed effects.

Analysis based on UA1 detector data.

Abstract

The shapes of invariant differential cross section for charged particle production as function of transverse momentum measured in pp collisions by the UA1 detector are analyzed. The spectra shape varies with the produced particle's pseudorapidity changing. To describe this and several other recently observed effects a simple qualitative model for hadroproduction mechanism was proposed.
