The Problem on the Lattice
L. Giusti, G. C. Rossi, M. Testa +1
If the expression of the topological charge density operator, suggested by fermions obeying the Ginsparg--Wilson relation, is employed, it is possible to prove on the lattice the v…

The U_A(1) Problem on the Lattice with Ginsparg-Wilson Fermions
L. Giusti, G. C. Rossi, M. Testa +1
We show how it is possible to give a precise and unambiguous implementation of the Witten--Veneziano formula for the eta' mass on the lattice, which looks like the formal continuum…

Non-perturbative improvement of lattice QCD at large momenta
G. Martinelli, G. C. Rossi, C. T. Sachrajda +3
We propose a method to improve lattice operators composed of Wilson fermions which allows the removal of all corrections of , including those proportional to the quark mass.…
