Abstract |
We have conducted a study of the B+(0) -> D & strns;D-0(-)(s0)& lowast;(2317)(+) reactions from the perspective that the D(s0)(& lowast;)0(2317) resonance is a molecular state of the DK and D-s eta components. We have followed a method to evaluate the branching fractions obtaining information from the experimental data on the B+ -> (DK+)-K-& strns;-K-0 D-0, B+ -> (DKD+)-K-& strns;0-D-0, B-0 -> D-K (+) D-0, B-0 -> (D-KD+)-D-0 reactions, which have the (DK +)-K-0 and (D+K0) pairs in the final state. The approach concentrates the dynamics of the weak process in the branching ratios of these reactions and pays attention to the propagation of the DK components and their strong interaction to form the D-s0(& lowast;)(2317) resonance. By means of two free parameters, we are able to describe these six rates, showing consistency with the molecular picture of the D-s0(& lowast;)(2317) state. |
