Masses From Novel Fat - Link Fermion Actions
The hadron mass spectrum is calculated in lattice QCD using a novel fatlink clover fermion action in which only the irrelevant operators in the fermion action are constructed using smeared links. The simulations are performed on a 16 × 32 lattice with a lattice spacing of a = 0.125 fm. We compare actions with n = 4 and 12 smearing sweeps with a smearing fraction of 0.7. The n = 4 Fat-Link Irrel...
متن کاملSimple Observables from Fat Link Fermion Actions
This paper is a continuation of earlier work [1,2] studying the properties of a particular type of improved action for studies of quenched QCD, with fermion-gauge field couplings parameterized by “fat links,” and a lattice anomalous magnetic moment “clover” term. One of the actions studied here has fermionic couplings extending over a hypercube. The other action is the fat link clover action. B...

متن کاملA Polynomial Hybrid Monte Carlo Algorithm
We present a simulation algorithm for dynamical fermions that combines the multiboson technique with the Hybrid Monte Carlo algorithm. We find that the algorithm gives a substantial gain over the standard methods in practical simulations. We point out the ability of the algorithm to treat fermion zero modes in a clean and controllable manner.
