Finite size of hadrons and Bose-Einstein correlations in $pp$ collisions at 7 TeV

TL;DR

This paper investigates how the finite size of hadrons affects Bose-Einstein correlations in proton-proton collisions at 7 TeV, using a blast-wave model to predict observable modifications in correlation functions.

Contribution

It introduces a theoretical analysis of finite hadron size effects on correlation functions in high-energy $pp$ collisions, based on a blast-wave model.

Findings

Finite hadron size induces measurable modifications in correlation functions.

The blast-wave model predicts specific changes in Bose-Einstein correlations.

Results suggest new ways to interpret correlation data in high-energy collisions.

Abstract

Space-time correlations between produced particles, induced by the composite nature of hadrons, imply specific changes in the properties of the correlation functions for identical particles. The expected magnitude of these effects is evaluated using the recently published blast-wave model analysis of the data for $pp$ collisions at $\sqrt{s}$ = 7 TeV.
