A perturbative study of the chirally rotated Schrödinger Functional in QCD

preprint2014arXivOpen access

Abstract

The chirally rotated Schrödinger functional (χχSF) renders the mechanism of automatic O(a)O(a) improvement compatible with the Schrödinger functional (SF) formulation. Here we report on the determination to 1-loop order in perturbation theory of the renormalization coefficients necessary to achieve automatic O(a)O(a) improvement and the boundary improvement coefficients needed to eliminate the extra boundary O(a)O(a) effects present in any SF formulation. After this is done, we perform a set of tests of automatic O(a)O(a) improvement and of the universality between standard and chirally rotated SF formulations.
