The force-force-correlator in hot QCD perturbatively and from the lattice

A bstract High-energy particles traversing a medium experience modified dispersion. In the Quark-Gluon Plasma, such dispersion affects jet propagation and transport properties should be determined better. Above ~ 2 T c we expect strongly coupled infrared behavior perturbative ultraviolet behavior, allowing matching to an effective theory called EQCD, which can studied non-perturbatively. We study relevant non-local operator in EQCD at next-to-leading order allows for complete EQCD-to-lattice match prepares groundwork between full QCD. Our results show remarkable agreement perturbation lattice expected regime.
