Clover improvement for stout-smeared 2+1 flavour SLiNC fermions: Non-perturbative results

Abstract

We discuss an action in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links for the clover term. With the (tree level) Symanzik improved gluon action this constitutes the Stout Link Non-perturbative Clover or SLiNC action. To cancel O(a) terms the clover coefficient, csw has to be tuned. We present here preliminary results of a non-perturbative determination of csw using the Schrödinger functional and as a by-product also a determination of the critical hopping parameter, kc. A determination of the renormalisation constant for the local vector current is also given. Comparisons of the results are made with lowest order perturbation theory results.
