Results from overlap valence quarks on a twisted mass sea
Nicolas Garron, Luigi Scorzato
We present results of lattice computations using overlap fermions on a twisted mass background. full QCD gauge configurations have been produced by the ETM Collaboration wi…
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 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…
Numerical simulations with two flavours of twisted-mass Wilson quarks and DBW2 gauge action
F. Farchioni, P. Hofmann, K. Jansen +9
Discretisation errors in two-flavour lattice QCD with Wilson-quarks and DBW2 gauge action are investigated by comparing numerical simulation data at two values of the bare gauge co…
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…
