Light meson decay constants beyond the quenched approximation
G. M. de Divitiis, R. Frezzotti, M. Guagnelli +2
We calculate the effects of including dynamical fermion loops in the lattice QCD estimates of meson decay constants, by extrapolating the results from negative flavour numbers afte…
The bermions: an approach to lattice QCD dynamical fermions from negative flavour numbers
G. M. de Divitiis, R. Frezzotti, M. Guagnelli +2
We estimate the effects of dynamical fermions by extrapolating to positive flavour numbers the results from negative values obtained by adding to the pure gauge sector a fermion ac…
Smeared propagators for lattice hadron spectroscopy
G. M. de Divitiis, R. Frezzotti, M. Guagnelli +2
We propose to replace ordinary propagators in lattice operator correlations entering the determination of hadron masses with space-time smeared propagators. These are defined as th…
