Quark bilinear step scaling functions and their continuum limit extrapolation
M. Guagnelli, J. Heitger, C. Pena, A. Vladikas
Abstract
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 the universality of the continuum limit for step scaling functions computed with different levels of O(a) improvement.
