Description
We report about a preliminary extraction of masses and decay constants of the lowest pseudoscalar B meson states from lattice simulations with Nf=2 Wilson-Clover dynamical quarks, using a procedure recently presented by the ALPHA Collaboration. The heavy quark is described by Heavy Quark Effective Theory developed up to 1/m_b. Coefficients of the effective theory have been determined non perturbatively by matching few observables with their QCD counterpart in the Schrödinger Functional framework. Hadronic matrix elements are obtained by solving a Generalised Eigenvalue Problem on a matrix of 2-pts correlators that have been computed on CLS ensembles. We have considered several lattice spacings and sea quark masses to deal with cut-off effects and chiral extrapolation.
