St¨¹ben %J Physics %D 2000 %I arXiv %X The improvement of simulations of QCD with dynamical Wilson fermions by combining the Hybrid Monte Carlo algorithm with parallel tempering is studied on $10^4$ and $12^4$ lattices. As an indicator for decorrelation the topological charge is used. %U http://arxiv.org/abs/hep-lat/0007039v1
