Two body non-leptonic decays of B and Bs mesons

We perform an analysis of two-body non-leptonic decays of B and B s mesons in the factorization approximation. We make use of the semileptonic decay amplitudes previously calculated on the basis of an effective lagrangian satisfying chiral and heavy quark symmetries and including spin 1 resonances....

Description
Summary:We perform an analysis of two-body non-leptonic decays of B and B s mesons in the factorization approximation. We make use of the semileptonic decay amplitudes previously calculated on the basis of an effective lagrangian satisfying chiral and heavy quark symmetries and including spin 1 resonances. Exclusive semileptonic D-decay data are used as experimental input. Our results compare favorably with data, whenever they are available, and indicate a positive value for the ratio of non-leptonic coefficients a 2 a 1 , similarly to previous studies.
