The shape of the static potential with dynamical fermions

Abstract

We present the analysis of the static potential extracted from Wilson loops measured on CLS ensembles generated with Wilson gauge action and Nf=2 flavors of O(a) improved Wilson quarks at three different lattice spacings and a range of quark masses. The shape of the static potential at distances well below the string breaking region is studied in terms of renormalized couplings derived from the static force and its derivative. We comment on the (im)possibility of extracting the Lambda parameter at our smallest lattice spacing a=0.05 fm. Finally we give an update on the scale determination through r0.
