O(a) improvement of the HYP static axial and vector currents at one-loop order of perturbation theory
A. Grimbach, D. Guazzini, F. Knechtli +1
We calculate analytically the improvement coefficients of the static axial and vector currents in O(a) improved lattice QCD at one-loop order of perturbation theory. The static qua…
Heavy-light mesons in lattice HQET and QCD
Damiano Guazzini
We present a study of a combination of HQET and relativistic QCD to extract the b-quark mass and the Bs-meson decay constant from lattice quenched simulations. We start from a smal…
Precision for B-meson matrix elements
Damiano Guazzini, Rainer Sommer, Nazario Tantalo
We demonstrate how HQET and the Step Scaling Method for B-physics, pioneered by the Tor Vergata group, can be combined to reach a further improved precision. The observables consid…
The B-meson mass splitting from non-perturbative quenched lattice QCD
A. G. Grozin, D. Guazzini, P. Marquard +4
We perform the non-perturbative (quenched) renormalization of the chromo-magnetic operator in Heavy Quark Effective Theory and its three-loop matching to QCD. At order 1/m of the e…
Heavy-strange meson decay constants in the continuum limit of quenched QCD
Michele Della Morte, Stephan Durr, Damiano Guazzini +3
We improve a previous quenched result for heavy-light pseudoscalar meson decay constants with the light quark taken to be the strange quark. A finer lattice resolution (a ~ 0.05 fm…
Non-perturbative renormalization of the chromo-magnetic operator in Heavy Quark Effective Theory and the B* - B mass splitting
Damiano Guazzini, Harvey B. Meyer, Rainer Sommer
We carry out the non-perturbative renormalization of the chromo-magnetic operator in Heavy Quark Effective Theory. At order 1/m of the expansion, the operator is responsible for th…
