Abstract

Description

We simulate Quantum Chromodynamics in four Euclidean dimensions with two (degenerate mass) flavors of dynamical quarks. The Dirac operator is the so-called chirally improved operator that has been studied so far in quenched calculations. We now present results of an implementation with the Hybrid Monte Carlo (HMC) algorithm including stout smearing. Our results are from an 8^3x16 lattice with tadpole improved Luescher-Weisz gauge action. We present our estimate of the lattice spacing, the pi and rho meson masses and evidence for tunneling between different topological sectors.
