چکیده

We present results from simulations of two dynamical flavors of improved Wilson fermions with nHYP smeared gauge links. We demonstrate that the simulation is stable at a pseudo-scalar mass of 360MeV, a 2.1fm box and a lattice spacing of 0.13fm.

Simulating dynamical fermions with smeared links

Smearing the gauge links of dynamical configurations removes small scale unphysical vacuum fluctuations and thus improves the chiral properties of lattice fermions. Recently we proposed the hypercubic smearing (HYP) that improves the flavor symmetry of staggered fermions by an order of magnitude with only minimal distortions at small distances. We describe a new algorithm to simulate dynamical ...

Simulation of dynamical fermions with smeared links

Smearing the gauge links of dynamical configurations removes small scale unphysical vacuum fluctuations und thus improves the chiral properties of lattice fermions. We present a new algorithm for the simulation of dynamical fermions coupled via smeared links based on the standard pure gauge overrelaxation and heatbath updatings. Smeared links play a fundamental role in making this algorithm eff...

Determination of the Static Potential with Dynamical Fermions

We present in detail a technique to extract the potential between a static quark and anti-quark pair from Wilson loops measured on dynamical configurations. This technique is based on HYP smearing and leads to an exponential improvement of the noise-to-signal ratio of Wilson loops. We explain why the correct continuum potential is obtained and show numerical evidence that the cut-off effects ar...

The non - perturbative O ( a ) - improved action for dynamical Wilson fermions ∗ Karl Jansen CERN 1211 Genève 23 Switzerland Rainer Sommer DESY - IfH Platanenallee 6 D - 15738 Zeuthen Germany

We compute the improvement coefficient csw that multiplies the Sheikholeslami-Wohlert term as a function of the bare gauge coupling for two flavour QCD. We discuss several aspects concerning simulations with improved dynamical Wilson fermions.
