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 constants for Lattice QCD: new results from Numerical Stochastic Perturbation Theory
Francesco Di Renzo, Vincenzo Miccio, Luigi Scorzato +1
By making use of Numerical Stochastic Perturbation Theory (NSPT) we can compute renormalization constants for Lattice QCD to high orders, e.g. three or four loops for quark bilinea…
Iterative methods for overlap and twisted mass fermions
T. Chiarappa, K. Jansen, K. -I. Nagai +6
We present a comparison of a number of iterative solvers of linear systems of equations for obtaining the fermion propagator in lattice QCD. In particular, we consider chirally inv…
