Unusual decay modes of D sup 0 and D sup + mesons

CLEO has measured decay modes of the {ital D}{sup 0} and {ital D}{sup +} into final states consisting of {ital K}{sup {plus minus}}'s, {pi}{sup {plus minus}}'s, {ital K}{sup 0}'s and {ital {bar K}}{sup 0}'s, using data taken with the CLEO detector at the Cornell Electron Storage...

Zusammenfassung:	CLEO has measured decay modes of the {ital D}{sup 0} and {ital D}{sup +} into final states consisting of {ital K}{sup {plus minus}}'s, {pi}{sup {plus minus}}'s, {ital K}{sup 0}'s and {ital {bar K}}{sup 0}'s, using data taken with the CLEO detector at the Cornell Electron Storage Ring. We report new results on the decays of {ital D}{sup 0}'s into 4{pi}{sup {plus minus}},{ital K}{sup {minus}}{ital K+}{pi}{sup {minus}}{pi}{sup +},{ital {bar K}}{sup 0}{ital K+}{ital K{minus}},{ital {bar K}}{sup 0} {ital K+}{pi}{sup {minus}},{ital K}{sup 0}{ital K{minus}}{pi}{sup +},3{ital K}{sub {ital S}}{sup 0} and {ital {bar K}}{sup 0}{phi} together with some of their resonant substructure. We also present the first observation of the decay {ital D}{sup +}{r arrow}{ital {bar K}}{sup 0}{ital {bar K}0}{ital K+} and give limits on the doubly-Cabibbo-suppressed decays of the {ital D}{sup 0} into {ital K}{sup +}{pi}{sup {minus}} and {ital K}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}}.
