TL;DR
This paper investigates how jet-momentum profiles in proton-proton collisions scale with event multiplicity, revealing underlying statistical properties of jet fragmentation through simulations and analytical parametrizations.
Contribution
It demonstrates the scaling behavior of jet profiles with multiplicity and links it to fundamental statistical properties of jet fragmentation, supported by Monte Carlo simulations and analytical models.
Findings
Jet radial profiles scale with charged-hadron multiplicity.
Parametrizations of jet profiles are provided based on statistical distributions.
Scaling behavior suggests a fundamental statistical origin of jet fragmentation.
Abstract
We study the structure of jets in proton-proton collisions at LHC energies using \textsc{Pythia} 8 Monte Carlo simulations. We demonstrate that the radial jet profiles exhibit scaling properties with charged-hadron event multiplicity over a broad transverse-momentum range. We also provide parametrizations of the jet profiles based on different statistically-motivated analytical distributions. Based on this we propose that the scaling behavior stems from fundamental statistical properties of jet fragmentation.
