“…Owing to the approximate flavor symmetry, the form factors of the decays are very close to their strange counterparts. A comparison of the form factors at from this study with those of other groups is shown in Tables 5−8, where the original values from LFQM [9,10], ISGW2 [7], and LCSRB [17] are converted to meet the current definitions of form factors using the formulae in Appendix B. We can see that large differences exist among the form factors given by different groups.…”

The form factors of B(s) decays into P-wave excited charmed mesons (including D* 0(2300), D1(2430), D1(2420), D* 2(2460) and their strange counterparts, denoted generically as D** (s)) are systematically calculated via the QCD sum rules in the framework of heavy quarkeffective field theory (HQEFT). We consider contributions up to the next leading order of heavy quark expansion and give all the relevant form factors, including the scalar and tensor ones which are only related to possible new physics effects. The expressions of form factors in terms of several universal wave functions are derived via the heavy quark expansion. These universal functions can be evaluated through QCD sum rules. Then the numerical results of form factors are presented. With the form factors given here, a model independent analysis of relevant semileptonic decays B(s)→D** (s) l νl is performed, including the contributions from possible new physics effects. Our predictions for the differential decay widths, branching fractions and the ratios of branching fractions R(D** (s)) may be tested by more precise experiments in the future.

We propose to investigate the effects of new physics in the semi-leptonic sequential decay [Formula: see text]. First, we write the general, model-independent, non-covariant expression of the differential decay width of the process. Then, we calculate that observable according to three different types of new physics interactions, which might explain the tension of data with the Standard Model predictions. We find that some coefficients of the differential decay width are sensitive to the kind of interaction that is assumed. The measurements that we suggest seem to be feasible.
