Gauge-independent extraction of the next-to-leading-order Debye mass from the gluon propagator
Abstract
Description
It is shown that by defining the Debye mass through the relevant pole of the static gluon propagator rather than the zero-momentum limit of the time-time component of the gluon self-energy, a gauge-independent result for the next-to-leading order correction can be derived upon resummation of hard-thermal-loop contributions. The result turns out to be logarithmically sensitive to the magnetic screening mass.
