Cutoff effects in twisted mass lattice QCD
2001
Journal of High Energy Physics
We present a first numerical study of lattice QCD with O(a) improved Wilson quarks and a chirally twisted mass term. Renormalized correlation functions are derived from the Schrödinger functional and evaluated in an intermediate space-time volume of size 0.75 3 × 1.5 fm 4 . In the quenched approximation precise results are then obtained with a moderate computational effort, allowing for a detailed study of the continuum approach. The latter is discussed in terms of observables which converge to
