Feasibility of searching for the Cabibbo-favored D* ? ?K? plus , ?K*? plus , ?K? plus decays

The current knowledge on the D* mesons is still inadequate. Encouraged by the positive development prospects of high-luminosity and high-precision experiments, the Cabibbo-favored nonleptonic D* ??? ??K??+, ??K*??+, ??K??+ weak decays are studied with the naive factorization approach. It is found that branching ratios of these processes can reach up to O(10???10) or more, and can be accessible at STCF, CEPC, FCC-ee, and LHCb@HL-LHC experiments in the future. It might even be possible to search for the D*0 ??? K*??? ??+ and K?????+ decays at the running SuperKEKB experiments. Superscript/Subscript Available更多
