We analyze the exclusive two-body nonleptonic decays of \(B_s \rightarrow M_{c\bar{c}}(1S,2S) K_s\) , induced by the \(b\rightarrow c\bar{c}d\) transition. Within the framework of relativistic independent quark model(RIQM) based on a flavor-independent interaction potential in scalar-vector harmonic form, we calculate the weak form factors from the overlapping integrals of meson wave function obtained in this model. Using the factorization approximation, we predict the branching fractions(BF) and ratio of BF, which can be compared with future theoretical predictions. Branching fractions for \(B_s\rightarrow \psi (1S,2S) K_s\) decays are found to be within the detection ability of the LHCb and CMS Collaborations resepectively. These results indicate that the present approach works well in the description of exclusive nonleptonic \(B_s\) decays within the framework of the RIQ model.

摘要

We analyze the exclusive two-body nonleptonic decays of \(B_s \rightarrow M_{c\bar{c}}(1S,2S) K_s\) , induced by the \(b\rightarrow c\bar{c}d\) transition. Within the framework of relativistic independent quark model(RIQM) based on a flavor-independent interaction potential in scalar-vector harmonic form, we calculate the weak form factors from the overlapping integrals of meson wave function obtained in this model. Using the factorization approximation, we predict the branching fractions(BF) and ratio of BF, which can be compared with future theoretical predictions. Branching fractions for \(B_s\rightarrow \psi (1S,2S) K_s\) decays are found to be within the detection ability of the LHCb and CMS Collaborations resepectively. These results indicate that the present approach works well in the description of exclusive nonleptonic \(B_s\) decays within the framework of the RIQ model.
