摘要：
Recent results relating to charm baryon and meson decays from the Belle and BABAR experiments are presented. In addition to recent observations for charm hyperons, evidence for a new charm baryon state, the A,(2940), observed in its decay to D(0)p is also reported. No evidence for doubly charmed baryons is seen in e(+)e(-) interactions. A measurement of the spin of the Omega(-) hyperon is made using decays of the and Omega(0)(c) baryons. On the assumption that the spin of the parent baryons are J = 1/2, the assignment J = 3/2 is confirmed and both J = 1/2 and also higher spins are excluded. New results on rare, Cabibbo-suppressed decays of charm mesons are also presented.
