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…
Four-loop lattice-regularized vacuum energy density of the three-dimensional SU(3) + adjoint Higgs theory
F. Di Renzo, M. Laine, Y. Schroder +1
The pressure of QCD admits at high temperatures a factorization into purely perturbative contributions from "hard" thermal momenta, and slowly convergent as well as non-perturbativ…
Towards 4-loop NSPT result for a 3-dimensional condensate-contribution to hot QCD pressure
C. Torrero, M. Laine, Y. Schroder +2
Thanks to dimensional reduction, the contributions to the hot QCD pressure coming from so-called soft modes can be studied via an effective three-dimensional theory named Electrost…
The strongly interacting Quark Gluon Plasma, and the critical behaviour of QCD at imaginary chemical potential
Massimo D'Elia, Francesco Di Renzo, Maria Paola Lombardo
We explore the highly non-perturbative hot region of the QCD phase diagram close to Tc by use of an imaginary chemical potential mu which avoids the sign problem. The number densit…
A Model for QCD at High Density and Large Quark Mass
R. De Pietri, A. Feo, E. Seiler +1
We study the high density region of QCD within an effective model obtained in the frame of the hopping parameter expansion and choosing Polyakov type of loops as the main dynamical…
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…
