A new method for taming tensor sum-integrals
Ioan Ghisoiu, York Schröder
We report on the computation of a class of massless bosonic three-loop vacuum sum-integrals which are key building blocks for an evaluation of the Debye screening mass in hot QCD.…
Three-loop matching coefficients for hot QCD: Reduction and gauge independence
Jan Moeller, York Schroder
We perform an integral reduction for the 3-loop effective gauge coupling and screening mass of QCD at high temperatures, defined as matching coefficients appearing in the dimension…
A new three-loop sum-integral of mass dimension two
I. Ghisoiu, Y. Schroder
We evaluate a new 3-loop sum-integral which contributes to the Debye screening mass in hot QCD. While we manage to derive all divergences analytically, its finite part is mapped on…
A fresh look on three-loop sum-integrals
Y. Schroder
In order to prepare the ground for evaluating classes of three-loop sum-integrals that are presently needed for thermodynamic observables, we take a fresh and systematic look on th…
IBP methods at finite temperature
M. Nishimura, Y. Schroder
We demonstrate the applicability of integration-by-parts (IBP) identities in finite-temperature field theory. As a concrete example, we perform 3-loop computations for the thermody…
Resummation scheme for 3d Yang-Mills and the two-loop magnetic mass for hot gauge theories
D. Bieletzki, K. Lessmeier, O. Philipsen +1
Perturbation theory for non-Abelian gauge theories at finite temperature is plagued by infrared divergences caused by magnetic soft modes , which correspond to the field…
