Non-perturbative results are obtained using the twistedmassWilson fermion formulation employing two degenerate dynamical quarks and the tree-level Symanzik improved gluon action for pion masses in the range of about 450-260 MeV and at there values of the lattice spacing, namely 0.055 fm, 0.070 fm and 0.089 fm. Subtraction of O(a^2) terms is carried out by performing the perturbative evaluation of these operators at 1- loop and up to O(a^2).
