Constituent quark model analysis of weak mesonic decays of charm baryons

In view of recent experimental trends we investigate the weak nonleptonic decays of charm baryons within the framework of the constituent quark model. Branching ratios and asymmetry parameters for all ${\mathrm{½}}^{+}$ → ${\mathrm{½}}^{+}$ + $0^{-}$ charm-changing modes are calculated with appropriate QCD corrections. The effect of flavor dependence on the scale is found to be quite significant.
