# A QCD Debye mass in a broad temperature range

@article{Laine2019AQD, title={A QCD Debye mass in a broad temperature range}, author={M. Laine and P. Schicho and Y. Schroder}, journal={Physical Review D}, year={2019}, volume={101} }

The Debye mass sets a scale for the screening of static charges and the scattering of fast charges within a gauge plasma. Inspired by its potential cosmological applications, we determine a QCD Debye mass at two-loop order in a broad temperature range (1 GeV–10 TeV), demonstrating how quark mass thresholds get smoothly crossed. Along the way, integration-by-parts identities pertinent to massive loops at finite temperature are illuminated.
