Universality of multiplicity distribution in proton-proton and electron-positron collisions

TL;DR

This paper suggests that the multiplicity distribution in proton-proton collisions can be derived from electron-positron collision data by considering the energy fluctuations of leading protons, indicating a possible universality across these collision types.

Contribution

It introduces a model linking $pp$ and $e^{+}e^{-}$ multiplicity distributions through energy fluctuation considerations, proposing a universal behavior.

Findings

Multiplicity distribution in $pp$ can be derived from $e^{+}e^{-}$ data.

Energy fluctuations of leading protons explain $pp$ multiplicity patterns.

Supports universality of particle production mechanisms.

Abstract

It is argued that the multiplicity distribution in proton-proton ($pp$) collisions, which is often parameterized by the negative binomial distribution, may result from the multiplicity distribution measured in electron-positron ($e^{+}e^{-}$) collisions, once the fluctuating energy carried by two leading protons in $pp$ is taken into account.
