Dynamical fat link fermions
The use of APE smearing or other blocking techniques in fermion actions can provide many advantages. There are many variants of these fat link actions in lattice QCD currently, such as FLIC fermions. Frequently, fat link actions make use of the APE blocking technique in combination with a projection of the blocked links back into the special unitary group. This reunitarisation is often performe...
متن کاملclover-improved Wilson fermions
We report calculations of the parameter BK appearing in the ∆S = 2 neutral kaon mixing matrix element, whose uncertainty limits the power of unitarity triangle constraints for testing the standard model or looking for new physics. We use two flavours of dynamical clover-improved Wilson lattice fermions and look for dependence on the dynamical quark mass at fixed lattice spacing. We see some evi...
متن کاملScaling and Eigenmode Tests of the Improved Fat Clover Action
We test the scaling properties of a recently proposed improved lattice-fermion action, the fat link clover action, for lattice spacing a = 0.09 and 0.16 fm. The action scales as well as the conventional nonperturbatively improved clover action. Tests done at small quark mass on quenched lattices of lattice spacing 0.12 fm show that it has fewer problems with pathological lattice artifacts (“exc...
متن کاملThermodynamics with Dynamical Clover Fermions
We investigate the finite temperature behavior of nonperturbatively improved clover fermions on lattices with temporal extent Nt = 4 and 6. Unfortunately in the gauge coupling range, where the clover coefficient has been determined nonperturbatively, the finite temperature crossover/transition occurs at heavy pseudoscalar masses and large pseudoscalar to vector meson mass ratios. However, on an...
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....
