Abstract
A first study of numerical Monte Carlo simulations with two quark doublets, a mass-degenerate one and a mass-split one, interpreted as u, d, s and c quarks, is carried out in the framework of the twisted mass Wilson lattice formulation. Tuning the bare parameters of this theory is explored on 123x24 and 163x32 lattices at lattice spacings a=0.20fm and a=0.15fm, respectively.
