Wilson fermions quark bilinears to three loops
F. Di Renzo, A. Mantovi, V. Miccio +2
Quark currents renormalization constants can in principle be safely computed in lattice perturbation theory. In practice, traditional lattice perturbative computations are quite cu…

Fermionic observables in Numerical Stochastic Perturbation Theory
V. Miccio, F. Di Renzo, A. Mantovi +2
We present technical details of fermionic observables computations in NSPT. In particular we discuss the construction of composite operators starting from the inverse Dirac operato…

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…
