Twisted-mass lattice QCD with mass non-degenerate quarks

R. Frezzotti, G. C. Rossi

The maximally twisted lattice QCD action of an doublet of mass degenerate Wilson quarks gives rise to a real positive fermion determinant and it is invariant under the pr…

Non-perturbative renormalization of moments of parton distribution functions

A. Shindler, M. Guagnelli, K. Jansen +3

We compute non-perturbatively the evolution of the twist-2 operators corresponding to the average momentum of non-singlet quark densities. The calculation is based on a finite-size…

Chirally improving Wilson fermions

R. Frezzotti, G. C. Rossi

It is possible to improve the chiral behaviour and the approach to the continuum limit of correlation functions in lattice QCD with standard and twisted Wilson fermions by taking a…

Quark bilinear step scaling functions and their continuum limit extrapolation

M. Guagnelli, J. Heitger, C. Pena +1

Some new results on nonperturbative renormalisation of quark bilinears in quenched QCD with Schroedinger Functional techniques are presented. Special emphasis is put on a study of…

Pion parton distribution functions from lattice QCD

I. Wetzorke, M. Guagnelli, K. Jansen +3

We report on recent results for the pion matrix element of the twist-2 operator corresponding to the average momentum of non-singlet quark densities. For the first time finite volu…

Heavy--light decay constants in the continuum limit of quenched lattice QCD

G. M. de Divitiis, M. Guagnelli, F. Palombi +2

We compute the decay constants for the heavy--light pseudoscalar mesons in the quenched approximation and continuum limit of lattice QCD. Within the Schrodinger Functional framewor…

Chirally improving Wilson fermions - I. O(a) improvement

R. Frezzotti, G. C. Rossi

We show that it is possible to improve the chiral behaviour and the approach to the continuum limit of correlation functions in lattice QCD with Wilson fermions by taking arithmeti…

Continuous external momenta in non-perturbative lattice simulations: a computation of renormalization factors

M. Guagnelli, K. Jansen, F. Palombi +3

We discuss the usage of continuous external momenta for computing renormalization factors as needed to renormalize operator matrix elements. These kind of external momenta are enco…
