Gluon screening mass at finite temperature from Landau gauge gluon propagator in lattice QCD
arXiv:1310.5629 · doi:10.1103/PhysRevD.89.074503
Abstract
We address the interpretation of the Landau gauge gluon propagator at finite temperature as a massive type bosonic propagator. Using pure gauge SU(3) lattice simulations at a fixed lattice volume $\sim(6.5fm)^3$, we compute the electric and magnetic form factors, extract a gluon mass from Yukawa-like fits, and study its temperature dependence. This is relevant both for the Debye screening at high temperature $T$ and for confinement at low $T$.
