Abstract

We present a search for the "wrong-sign" decay D⁰ → Κ⁺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 → Κ^-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.
