Encouraged by the positive development prospects of high-luminosity and high-precision experiments, the Cabibbo-favored nonleptonic $D^{\\ast}$ ${\\to}$ $\\overline{K}{\\pi}^{+}$, $\\overline{K}^{\\ast}{\\pi}^{+}$, $\\overline{K}{\\rho}^{+}$ weak decays are studied with the naive factorization approach. It is found that branching ratios of these processes can reach up to ${\\cal O}(10^{-9})$ or more, and that there will be hundreds or thousands of events accessible at STCF, CEPC, FCC-ee and LHCb@HL-LHC experiments in the future. It might even be possible to search for the $D^{{\\ast}+}$ ${\\to}$ $K^{{\\ast}-}{\\pi}^{+}$ and $K^{-}{\\rho}^{+}$ decays at the running SuperKEKB experiments.", "revisions": [ { "version": "v1", "updated": "2022-07-21T03:09:08.000Z" } ], "analyses": { "keywords": [ "feasibility", "naive factorization approach", "running superkekb experiments", "positive development prospects", "weak decays" ], "note": { "typesetting": "TeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable" } } }
