Spectral-function determination of complex electroweak amplitudes with lattice QCD
R. Frezzotti, G. Gagliardi, V. Lubicz +3
We present a novel method to determine on the lattice both the real and imaginary parts of complex electroweak amplitudes involving two external currents and a single hadron or the…

First direct lattice calculation of the chiral perturbation theory low-energy constant
R. Frezzotti, G. Gagliardi, V. Lubicz +3
We evaluate by means of lattice QCD calculations the low-energy constant which parametrizes strong isospin effects at NLO in chiral perturbation theory. Amo…

Rotated twisted-mass: a convenient regularization scheme for isospin breaking QCD and QED lattice calculations
R. Frezzotti, G. Gagliardi, V. Lubicz +2
We propose a scheme of lattice twisted-mass fermion regularization which is particularly convenient for application to isospin breaking (IB) QCD and QED calculations, based in part…
