TL;DR
This paper uses lattice EQCD to accurately determine the collisional broadening kernel in QCD plasmas, analyzing its behavior and application to medium-induced radiation rates.
Contribution
It provides a non-perturbative calculation of the collisional broadening kernel with correct UV limits, advancing understanding of medium effects in QCD plasmas.
Findings
Determined the collisional broadening kernel $C(b_\perp)$ using lattice EQCD.
Analyzed the behavior of $C(b_\perp)$ at small and large impact parameters.
Showed how the kernel can be used to compute medium-induced radiation rates.
Abstract
We supply recently obtained results from lattice EQCD with the correct UV limit to construct the collisional broadening kernel in a QCD plasma. We discuss the limiting behavior of at small and large impact parameters , and illustrate how the results can be used to compute medium-induced radiation rates.
