abstract
We study two-body weak decays of charmed baryons \Lambda_c and \Xi_c into an octet or decuplet baryon and a pseudoscalar meson employing the SU(3) flavor symmetry. Using certain measured Cabibbo-favored modes, we fix the reduced amplitudes and predict the branching ratios of various decays of charmed baryons in the Cabibbo-enhanced, -suppressed and -doubly suppressed modes.

The Cabibbo-favored hadronic weak decays of the $\Xi_c$ in the quark model
Using direct meson emission, color suppressed, and pole terms in a quark model, the authors reproduce most measured Xi_c decay branching ratios and predict asymmetry parameters, while failing one measured asymmetry sign.
