Numerical Stochastic Perturbation Theory for full QCD
F. Di Renzo, L. Scorzato
We give a full account of the Numerical Stochastic Perturbation Theory method for Lattice Gauge Theories. Particular relevance is given to the inclusion of dynamical fermions, whic…
The n_f=2 residual mass in lattice HQET to alpha^3 order
F. Di Renzo, L. Scorzato
We compute the so called residual mass in Lattice Heavy Quark Effective Theory to alpha^3 order in the n_f=2 (unquenched) case. The control of this additive mass renormalization is…
3-d lattice SU(3) free energy to four loops
F. Di Renzo, A. Mantovi, V. Miccio +2
We report on the perturbative computation of the 3d lattice Yang-Mills free energy to four loops by means of Numerical Stochastic Perturbation Theory. The known first and second or…
Two and three loops computations of renormalization constants for lattice QCD
F. Di Renzo, A. Mantovi, V. Miccio +2
Renormalization constants can be computed by means of Numerical Stochastic Perturbation Theory to two/three loops in lattice perturbation theory, both in the quenched approximation…
3-d Lattice QCD Free Energy to Four Loops
F. Di Renzo, A. Mantovi, V. Miccio +1
We compute the expansion of the 3-d Lattice QCD free energy to four loop order by means of Numerical Stochastic Perturbation Theory. The first and second order are already known an…
