摘要
In this study, we investigate the nonleptonic decays of the charmed-baryon 0c induced by the c-* u(dd<overline>)/(ss<overline>) transition. Utilizing the factorization assumption, we decompose the decay amplitudes in terms of transition form factors which are then calculated within the light-front quark model. We employ helicity amplitudes to analyze the nonleptonic decay modes of the charmed-baryons 0c and derive benchmark results for decay widths and branching fractions. Our calculations suggest that the branching fractions for some of these rare nonleptonic decays are at the order of 10-5-10-4, which are likely to be detectable at experiments such as LHCb, Belle-II, etc. The potential data accumulated in the future may help to further our understanding of the decay mechanism in the presence of charm quarks.
