Improved analysis of the scalar and vector form factors of kaon semileptonic decays with N_f = 2 twisted-mass fermions
V. Lubicz, F. Mescia, L. Orifici +2
We investigate the vector and scalar form factors relevant for K_{\ell 3} semileptonic decays using maximally twisted-mass fermions with two flavors of dynamical quarks (N_f = 2).…
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…
Heavy-Quark Mass and Heavy-Meson Decay Constants from QCD Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present a sum-rule extraction of heavy-meson decay constants from the two-point correlator of heavy-light pseudoscalar currents. Our main concern is to control the uncertainties…
Quark masses with Nf=2 twisted mass lattice QCD
B. Blossier, P. Dimopoulos, R. Frezzotti +6
We present the results of the recent high precision lattice calculation of the average up/down, strange and charm quark masses performed by ETMC with Nf=2 twisted mass Wilson fermi…
Quark-Hadron Duality and Effective Continuum Thresholds in Dispersive Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
A novel procedure for extracting hadron characteristics from QCD sum rules, based on effective continuum thresholds (necessary for the implementation of quark-hadron duality) which…
