Jet substructure of light and heavy flavor jets at RHIC

TL;DR

This study uses Monte Carlo simulations to analyze jet substructure in proton-proton collisions at RHIC energies, aiming to test models of non-perturbative QCD effects and adapt measurements for the sPHENIX experiment.

Contribution

It extends jet substructure analysis to lower energies at RHIC, focusing on heavy flavor jets and the dead cone effect, which has been less explored compared to LHC energies.

Findings

Demonstrates feasibility of measuring jet substructure at RHIC energies.

Highlights the impact of dead cone effect on jet angularities.

Provides a framework for future experimental studies at sPHENIX.

Abstract

Jet substructure studies at the Large Hadron Collider have been used to constrain parton distribution functions, test perturbative QCD, measure the strong-coupling constant, and probe the properties of the quark-gluon plasma. We extend these studies to lower energies at the Relativistic Heavy Ion Collider that would additionally allow us to test existing models of non-perturbative physics. In this study, we present a PYTHIA8-based Monte Carlo study of substructure of jets produced in $p+p$ collisions at 200 GeV. The selection criteria is adapted for a feasible measurement at sPHENIX. We consider different types of jet substructure observables such as jet angularities and primary Lund Plane with a special focus on suppression of collinear radiation around emitting heavy quark known as a dead cone effect.
