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