Possibility of experimental study on nonleptonic weak decays

The ground vector meson has not yet been experimentally discovered until now. Besides the dominant electromagnetic decays, nonleptonic weak decays provide another choice to search for the mysterious mesons. Inspired by the potential prospects of mesons in future high-luminosity colliders, nonleptonic weak decays induced by bottom and charm quark decays are studied within the SM by using a naive factorization approach. It is found that for , , , , , , , and decays, a few hundred and even thousands of events might be observable in CEPC, FCC-ee and LHCb@HL-LHC experiments.
