Abstract The QCD-enhanced effective weak hamiltonian for the Weinberg-Salam model including hardgluonic corrections is used to calculate the experimentally measured ratio $$\Gamma (\Lambda _c^ + \to p\bar K^0 )/\Gamma (\Lambda _c^ + \to \Lambda \pi ^ + )$$ . The same effective weak hamiltonian was used to describeD→K π decays. In these decays, it failed; agreement with experiments was possible only when some soft-gluonic effects were included. The same situation is encountered in charmed-baryon decays. Predictions are also given for theΛ c + →Ξ 0 K +,Λ c + →Λ ++ K − and $$\Lambda _c^ + \to \Lambda ^ + \bar K^0 $$ decays.
