TL;DR
This paper investigates the infrared behavior of the gluon propagator in SU(2) lattice gauge theory at zero and finite temperatures, revealing a persistent massive behavior with temperature-dependent characteristics.
Contribution
It provides new lattice simulation results showing the massive nature of the gluon propagator persists at finite temperature and discusses its analytic implications.
Findings
Massive gluon propagator observed at zero temperature
Massive behavior persists at finite temperature in electric and magnetic channels
Differences in behavior between electric and magnetic channels at finite temperature
Abstract
We report on our study of the infrared gluon propagator for SU(2) lattice gauge theory using large lattice volumes. The observed massive behavior is discussed from the point of view of analytic predictions for the zero-temperature case. Such a behavior is still present as the temperature is switched on, but manifests itself differently in the electric and magnetic channels.
