Forward-backward Asymmetry and Branching Ratio of B K1 + - Transition in Supersymmetric Models
Abstract
The mass eigen states K1(1270) and K1(1400) are mixture of the strange members of two axial-vector SU(3) octet, 3P1(K1A) and 1P1(K1B). Taking into account this mixture, the forward-backward asymmetry and branching ratio of B K1(1270,1400) + - transitions are studied in the framework of different supersymmetric models. It is found that the results have considerable deviation from the standard model predictions. Any measurement of these physical observables and their comparison with the results obtained in this paper can give useful information about the nature of interactions beyond the standard model.
