Axial-Vector Emitting Weak Nonleptonic Deacys of ${\Omega }_c^0$ Baryon

Abstract

The axial-vector emitting weak hadronic decays of ${\Omega }_c^0$ 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 ${\Omega }_c^0$ baryon.
