Multiplicity dependence of correlation functions in \bar{p}p reactions at sqrt(s) = 630 GeV

TL;DR

This paper investigates how particle correlation functions depend on event multiplicity in antiproton-proton collisions at 630 GeV, focusing on the effects of multiple string production on Bose-Einstein correlations.

Contribution

It provides the first detailed analysis of multiplicity dependence of correlation functions in ar{p}p reactions at this energy, addressing the impact of multiple string production.

Findings

Correlation functions vary with multiplicity.

Like-sign and opposite-sign pairs show different behaviors.

Results inform models of particle production and Bose-Einstein correlations.

Abstract

Discussions about Bose-Einstein correlations between decay products of coproduced W-bosons again raise the question about the behaviour of correlations if several strings are produced. This is studied by the multiplicity dependence of correlation functions of particle pairs with like-sign and opposite-sign charge in \bar{p}p reactions at sqrt{s} = 630 GeV.
