Abstract
We present a search for the “wrong-sign” decay using of collisions on and just below the resonance. This decay can occur either through a doubly Cabibbo-suppressed process or through mixing to a followed by a Cabibbo-favored process. Our result for the time-integrated wrong-sign rate relative to the decay is space), which has a statistical significance of 3.9 standard deviations.
