Non-perturbative O(a) improvement of the vector current

arXiv:hep-lat/9709088 · doi:10.1016/S0920-5632(97)00930-4

Abstract

We discuss non-perturbative improvement of the vector current, using the Schroedinger Functional formalism. By considering a suitable Ward identity, we compute the improvement coefficient which gives the O(a) mixing of the tensor current with the vector one.
