The continuum limit of the quark mass step scaling function in quenched lattice QCD
M. Guagnelli, J. Heitger, F. Palombi +2
The renormalisation group running of the quark mass is determined non-perturbatively for a large range of scales, by computing the step scaling function in the Schroedinger Functio…
Finite size effects of a pion matrix element
M. Guagnelli, K. Jansen, F. Palombi +3
We investigate finite size effects of the pion matrix element of the non-singlet, twist-2 operator corresponding to the average momentum of non-singlet quark densities. Using the q…
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…
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…
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…
