Description
We present the results for the normalization of the relevant form factor mediating the semileptonic B-->Dlnu and Bs-->Ds lnu decays in the Standard Model, as obtained by using the maximally twisted mass QCD on the lattice with Nf=2 dynamical light quarks, and with the fully propagating heavy quark. Furthermore, the form factors needed for description of these decays in a generic scenarios of physics beyond the Standard Model near zero recoil are also presented.
Preliminary results for F(1), needed to normalize B-->D* lnu and Bs-->Ds* lnu decays, are also presented in this talk.
