Controlling quark mass determinations non-perturbatively in three-flavour QCD
Isabel Campos, Patrick Fritzsch, Carlos Pena +3
The determination of quark masses from lattice QCD simulations requires a non-perturbative renormalization procedure and subsequent scale evolution to high energies, where a conver…
K^0-\bar{K}^0 Mixing Beyond the SM from Nf=2 tmQCD
ETM Collaboration, P. Dimopoulos, R. Frezzotti +8
We present preliminary results on the of neutral kaon oscillations in extensions of the Standard Model. Using Nf=2 maximally twisted sea quarks and Osterwalder-Seiler valence quark…
Non-perturbative scale evolution of four-fermion operators in two-flavour QCD
ALPHA Collaboration, P. Dimopoulos, G. Herdoiza +4
We apply finite-size recursion techniques based on the Schrodinger functional formalism to determine the renormalization group running of four-fermion operators which appear in the…
A precise determination of in quenched QCD
P. Dimopoulos, J. Heitger, F. Palombi +3
The parameter is computed in quenched lattice QCD with Wilson twisted mass fermions. Two variants of tmQCD are used; in both of them the relevant four-fermion operat…
