We have used the gauge configurations produced by the European Twisted Mass collaboration with N-f = 2 dynamical quarks, at four lattice spacings and light meson masses in the range 280-500 MeV. Renormalization is carried out nonperturbatively with the regularization-independent momentum subtraction method. The bag-parameter results have been used to constrain new physics effects in D-0 – (D) over bar (0) mixing, to put a lower bound to the generic new physics scale and to constrain off-diagonal squark mass terms for TeV-scale supersymmetry. %R 10.1103/PhysRevD.90.014502 %U http://arxiv.org/abs/arXiv:1403.7302 %U https://doi.org/10.1103/PhysRevD.90.014502 %P 014502-9pp
