Abstract

We present results of a hybrid Monte-Carlo algorithm for dynamical, n_f = 2, four-dimensional QCD with overlap fermions. The fermionic force requires careful treatment, when changing topological sectors. The pion mass dependence of the topological susceptibility is studied on 6⁴ and 12·6³ lattices. The results are transformed into physical units.
