Present and future experiments will reach unprecedented precision in the measurements of physical quantities related to B-physics. An accurate theoretical determination of intrinsically non-perturbative parameters, relevant for studies of B-physics, is therefore required in many phenomenological analysis to further constrain the Standard Model and to explore New Physics scenarios.
The goal of lattice QCD calculations is to provide the required non-perturbative information with competitive statistical and systematic errors. Despite the intrinsic difficulties in studying the non-perturbative dynamics of the b-quark with currently numerically affordable lattice spacings, B-physics quantities can still be calculated with high precision.
I will present results for selected physical quantities obtained adopting a newly developed method.
