The Λc and its inclusive nonleptonic decay

The inclusive nonleptonic decay of the Λ_c⁺ is reanalyzed using a nonrelativistic quark model representation of the Λ_c⁺- wavefunction. It is shown that the same approximation which leads to the familiar spectator and annihilation type contributions naturally also gives interference terms as a direct consequence of Fermi statistics. Numerical estimates which include these novel contributions, are presented for the Λ_c⁺ lifetime and semileptonic branching ratio.
