O(a) improvement of the HYP static axial and vector currents at one-loop order of perturbation theory
We calculate analytically the improvement coefficients of the static axial and vector currents in O(a) improved lattice QCD at one-loop order of perturbation theory. The static quark is described by the hypercubic action, previously introduced in the literature in order to improve the signal-to-nois...
