B-physics from N_f = 2 tmQCD: the Standard Model and beyond

We present a lattice QCD computation of the b-quark mass, the B and B _s decay constants, the B-mixing bag prameters for the full four-fermion operator b...

Kaon mixing beyond the SM from N_f = 2 tmQCD and model independent constraints from the UTA

We present the first unquenched, continuum limit, lattice QCD results for the matrix elements of the operators describing neutral kaon oscillations in extensions of the Standard Model. Owing to the accuracy of...

Non-perturbative renormalization of quark bilinear operators with N _f = 2 (tmQCD) Wilson fermions and the tree-level improved gauge action

We present results for the renormalization constants of bilinear quark operators obtained by using the tree-level Symanzik improved gauge action and the N _{f ...}
