Scaling of hadronic observables in QCD with Nf=2 maximally twisted Wilson quarks

Presenter: Roberto Frezzotti — Univ. and INFN of Rome Tor Vergata

Roberto Frezzotti

I present results for the scaling of simple hadronic observables computed by large-scale simulations of lattice QCD with two dynamical twisted mass Wilson quarks. I also discuss the relation between tuning of the untwisted mass to its optimal critical value and the control of O(a2) cutoff effects at small quark masses.
