The Landau gauge lattice ghost propagator in stochastic perturbation theory
F. Di Renzo, E. -M. Ilgenfritz, H. Perlt +2
We present one- and two-loop results for the ghost propagator in Landau gauge calculated in Numerical Stochastic Perturbation Theory (NSPT). The one-loop results are compared with…
High loop renormalization constants by NSPT: a status report
Francesco Di Renzo, Luigi Scorzato, Christian Torrero
We present an update on Numerical Stochastic Perturbation Theory projects for Lattice QCD, which are by now run on apeNEXT. As a first issue, we discuss a strategy to tackle finite…
High-loop perturbative renormalization constants for Lattice QCD (I): finite constants for Wilson quark currents
F. Di Renzo, V. Miccio, L. Scorzato +1
We present a high order perturbative computation of the renormalization constants Z_V, Z_A and of the ratio Z_P/Z_S for Wilson fermions. The computational setup is the one provided…
Renormalization of infrared contributions to the QCD pressure
C. Torrero, M. Laine, Y. Schroder +2
Thanks to dimensional reduction, the infrared contributions to the QCD pressure can be obtained from two different three-dimensional effective field theories, called the Electrosta…
