Are Cabibbo suppressed decays really suppressed in D$^{+}$ decays?
Two classes of proposals have been made to account for the 'anomalies' reported in charm decays, namely (a) strong 20-plet dominance and (b) W exchange. It is pointed out that 20-plet dominance leads to rather striking effects for the Cabibbo disfavoured decays of D/sup +/, namely the abse...

| Sumario: | Two classes of proposals have been made to account for the 'anomalies' reported in charm decays, namely (a) strong 20-plet dominance and (b) W exchange. It is pointed out that 20-plet dominance leads to rather striking effects for the Cabibbo disfavoured decays of D/sup +/, namely the absence of strong Cabibbo suppression. The W exchange mechanism does not seem to lead to such effects. (16 refs). |
