Abstract

We present a search for the "wrong-sign" decay D0→K+π-π+π - using 9 fb-1 of e+e- collisions on and just below the Y(4S) resonance. This decay can occur either through a doubly Cabibbo-suppressed process or through mixing to a D̄0 followed by a Cabibbo-favored process. Our result for the time-integrated wrong-sign rate relative to the decay D0→K-π+π-π + is (0.0041-0.0011 +0.0012(stat)±0.0004(syst)) ×(1.07±0.10)(phase space), which has a statistical significance of 3.9 standard deviations.
