摘要：We report on simulation results with overlap hypercube fermions (overlap HF) — a type of exactly
chiral lattice fermions — and their link to chiral perturbation theory. We first sketch the
construction of the overlap HF and discuss its high level of locality. Next we show applications
in the p-regime of QCD, where we evaluate mp , mr , the quark mass according to the PCAC relation,
the renormalisation constant ZA and the pion decay constant Fp as functions of the bare
quark mass. Fp is then reconsidered at even smaller quark masses in the e -regime, along with
the scalar condensate S. In that context we also discuss results for the topological charges and
susceptibility.
