Download or read book Determination of the Wrong Sign Decay Rate D0 -] K+pi- and the Sensitivity to D0-D0bar Mixing written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The D[sup 0] meson can decay to the wrong sign K[sup+][pi][sup -] state either through a doubly Cabibbo suppressed decay or via mixing to the[bar D][sup 0] state followed by the Cabibbo favoured decay[bar D][sup 0][yields] K[sup+][pi][sup -]. We measure the rate of wrong sign decays relative to the Cabibbo favoured decay to (0.383[+-] 0.044[+-] 0.022)% and give our sensitivity to a mixing signal.
