Non-perturbative improvement of stout-smeared three flavour clover fermions
We discuss a 3-flavour lattice QCD action with clover improvement 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 term coefficient has to be tuned. We pre...
متن کاملClover improvement for stout-smeared 2+1 flavour SLiNC fermions: perturbative results
For the Stout Link Non-perturbative Clover (SLiNC) action we determine in one-loop lattice perturbation theory the critical hopping parameter κc and the clover parameter cSW which is needed for O(a) improvement. Performing this calculation off-shell we are also able to compute the non gauge invariant quark field improvement coefficient cNGI . Additionally, we present first results for the renor...
متن کاملLight quark simulations with FLIC fermions
Hadron masses are calculated in quenched lattice QCD in order to probe the scaling behavior of a novel fatlink clover fermion action in which only the irrelevant operators of the fermion action are constructed using APE-smeared links. Light quark masses corresponding to an mπ/mρ ratio of 0.35 are considered to assess the exceptional configuration problem of clover-fermion actions. This Fat-Link...
متن کاملNon-perturbative improvement of nHYP smeared Wilson fermions
Using Schrödinger functional techniques, we determine the coefficient of the clover term necessary for non-perturbative O(a) improvement of hypercubic smeared Wilson fermions on a quenched plaquette action background. Unlike for unsmeared Wilson fermions, the resulting clover coefficients are close to the tree–level value even at coarse lattice spacings, indicating the absence of large cutoff e...
متن کاملPerturbative determination of cSW for plaquette and Symanzik gauge action and stout link clover fermions
Using plaquette and Symanzik improved gauge action and stout link clover fermions we determine the improvement coefficient cSW in one-loop lattice perturbation theory from the off-shell quark-quark-gluon three-point function. In addition, we compute the coefficients needed for the most general form of quark field improvement and present the one-loop result for the critical hopping parameter κc....
