K -> pi matrix elements of the chromagnetic operator on the lattice
M. Constantinou, M. Costa, R. Frezzotti +5
We present preliminary results of the first lattice QCD calculation of the K -> pi matrix elements of the chromomagnetic operator O_{CM}=g sbar sigma_{munu} G_{munu} d, which appea…
D-Dbar Mixing in the Standard Model and Beyond from Nf=2 Twisted Mass QCD
N. Carrasco, M. Ciuchini, P. Dimopoulos +8
We present the first unquenched lattice QCD results for the bag parameters controlling the short distance contribution to D meson oscillations in the Standard Model and beyond. We…
Up, down, strange and charm quark masses with Nf = 2+1+1 twisted mass lattice QCD
N. Carrasco, A. Deuzeman, P. Dimopoulos +16
We present a lattice QCD calculation of the up, down, strange and charm quark masses performed using the gauge configurations produced by the European Twisted Mass Collaboration wi…
A non-perturbative mechanism for elementary particle mass generation
R. Frezzotti, G. C. Rossi
Taking inspiration from lattice QCD data, we argue that a finite non-perturbative contribution to the quark mass is generated as a consequence of the dynamical phenomenon of sponta…
