摘要
We study the decays B over bar 0 - over bar K0X, B- - K-X, B over bar 0s - eta(eta 1)X, B over bar 0 - over bar K*0X, B- - K*-X, B over bar 0s - phi X, with X equivalent to X(3872), from the perspective of the X(3872) being a molecular state made from the interaction of the D*+D-; D*0 over bar D0, and c:c: components. We consider both the external and internal emission decay mechanisms and find an explanation for the over bar K0X and K-X production rates, based on the mass difference of the charged and neutral D*D over bar components. We also find that the internal and external emission mechanisms add constructively in the B over bar 0 - over bar K0X, B- - K-X reactions, while they add destructively in the case of widths of the present measurements and allows us to make predictions for the unmeasured modes of B over bar 0s - eta(eta 1)X(3872) and B- - K*-X(3872). The future measurement of these decay modes will help us get a better perspective on the nature of the X(3872) and the mechanisms present in production reactions of that state. B over bar 0 - over bar K*0X, B- - K*-X reactions. This feature explains the decay
