Abstract

A study investigating a possible jet shape dependence on the charged event multiplicity was performed on collision samples generated by Monte–Carlo (MC) event generators Pythia and Hijing++. We calculated the integral jet shape and found a significant modification caused by multiple-parton interactions. By interchanging and enabling different model ingredients in the simulations and analyzing the results in several p T bins and event multiplicity classes, we found a characteristic jet size measure that was independent of the chosen tunes, settings, and jet reconstruction algorithms.
Keywords: jet physics; jet structure; jet shapes; color reconnection; multiple-parton interactions; high-energy collisions jet physics; jet structure; jet shapes; color reconnection; multiple-parton interactions; high-energy collisions
