TL;DR
This paper investigates the behavior of the ghost propagator in pure gauge SU(3) Yang-Mills theory at finite temperature, revealing its potential as an indicator of the deconfinement phase transition through lattice QCD simulations.
Contribution
It provides the first lattice QCD analysis of the ghost propagator across the deconfinement transition in SU(3) Yang-Mills theory, highlighting its enhancement at high temperatures.
Findings
Ghost propagator is enhanced above T_c
Potential use of ghost propagator as phase transition indicator
Supports previous gluon propagator findings
Abstract
The ghost propagator in Landau gauge is studied at finite temperature below and above using lattice QCD simulations. For high temperatures, we find that the ghost propagator is enhanced, compared to the confined phase. The results suggest that the ghost propagator can be used to identify the phase transition, similarly to the gluon propagator case.
