Abstract

The axial-vector-emitting weak hadronic decays of the Ωc0 baryon are investigated. After employing the factorization and the pole model framework to predict their branching ratios, we derive the symmetry-breaking effects on axial-vector-meson-baryon couplings and effects of flavor dependence on baryon-baryon weak transition amplitudes and, consequently, on their branching ratios. We found that the W-exchange process contributions dominate p-wave-meson emitting decays of the Ωc0 baryon.
