Content
The long-standing infrared problem that seems to obstruct weak-coupling determinations
of the hot QCD pressure has been overcome by a systematic use of dimensionally re- duced effective theories (drEFT), essentially mapping the problem to determining one non- perturbative contribution plus a number of purely perturbative matching coefficients.
We focus on the latter problem and propose to apply a systematic integrand mapping algorithm that has recently been successfully applied to one of those matching coefficients [1] to the determination of the so-called Debye screening mass that describes the screening of color-electric gluonic modes in the hot QCD plasma.
