Abstract
We report the first reconstruction in hadron collisions of the suppressed decays and , sensitive to the Cabibbo-Kobayashi-Maskawa phase , using data from of integrated luminosity collected by the CDF II detector at the Tevatron collider. We reconstruct a signal for the suppressed mode with a significance of 3.2 standard deviations, and measure the ratios of the suppressed to favored branching fractions , , as well as the direct -violating asymmetry of this mode. Corresponding quantities for decay are also reported.
