NONLEPTONIC CABIBBO FAVORED B-DECAYS AND CP-ASYMMETRIES FOR CHARMED FINAL HADRON STATES IN ISGUR AND WISE THEORY

The Cabibbo allowed non-leptonic B-decays in two hadrons are studied, within the factorization hypothesis, in the framework of Isgur and Wis e theory for the matrix elements of the DELTAB = - DELTAC = +/- 1 weak currents. The SU(2)HF symmetry relates \DELTAB\ = 1 to \DELTAC\ = 1 c urrents, which have been measured in the semileptonic strange decays o f charmed particles. By assuming colour screening and allowing for SU( 3) invariant contributions from the annihilation terms with charmed fi nal states one is able to comply with the present experimental knowled ge. The CP violating asymmetries in neutral B decays are given for cha rmed final states in terms of the K-M angles. With the central values found for the annihilation parameters there is a destructive (construc tive) interference between the direct and annihilation terms in the Ca bibbo allowed (doubly forbidden) amplitudes for the decays into D0(D0 )pi0 and D0rho0 so that they may be of the same order. This would impl y large asymmetries, for which however our present knowledge on the am plitudes does not allow to predict even their sign. We have better con fidence in our predictions for the charged final states than the neutr al ones and can draw the conclusion that the detection of the correspo nding asymmetries requires, at least, 10(6) tagged neutral B-particles .
