Quark mass effects in quark number susceptibilities
Thorben Graf, Peter Petreczky
TL;DR
This paper investigates how quark masses influence quark number susceptibilities in the quark-gluon plasma using advanced perturbation theory and compares the results with lattice QCD data.
Contribution
It introduces a next-to-leading-order perturbative approach that explicitly incorporates quark mass effects and benchmarks it against lattice QCD results.
Findings
Mass effects significantly impact quark number susceptibilities.
Perturbative results show good agreement with lattice data for certain conditions.
Highlights the importance of including quark masses in QGP studies.
Abstract
The quark degrees of freedom of the QGP with special focus on mass effects are investigated. A next-to-leading-order perturbation theory approach with quark mass dependence is applied and compared to lattice QCD results.
