Abstract
Baryon-baryon matrix elements of the parity-violating charm-changing weak Hamiltonian are calculated using the MIT bag model. The changes in thes- andp-wave amplitudes of Cabibbo-favored nonleptonic decays of charmed baryons due to these parity-violating baryon transition elements are in general not substantially significant. However, they can overwhelm or be comparable to the contributions arising from the parity-conserving matrix elements for some reactions such as thes-wave amplitude ofΛ +c →Ξ 0 K + and Δ++ K − and thep-wave amplitude ofΛ +c →∑ 0π+.
