Measurements of higher-order cumulants of multiplicity and net-electric charge distributions in inelastic proton-proton interactions by NA61/SHINE

Abstract

This paper presents the energy dependence of multiplicity and net-electric charge fluctuations in $p+p$ interactions at beam momenta 20, 31, 40, 80, and 158 GeV/$c$. Results are corrected for the experimental biases and quantified with the use of cumulants and factorial cumulants. Data are compared with the Epos1.99 and FTFP-BERT model predictions
