Scaling and low energy constants in lattice QCD with N_f=2 maximally twisted Wilson quarks

Understand

We report on the scaling of basic hadronic observables in lattice QCD with N_f=2 maximally twisted Wilson dynamical quarks.

• We give preliminary results for some of the Gasser-Leutwyler low energy constants, the chiral condensate and the average mass of u and d quarks.
