Measurement of the branching fraction B(?b0??c+p -p +p -) at CDF

Abstract: We report an analysis of the 0b ! þc þ decay in a data sample collected by the CDF II detector at the Fermilab Tevatron corresponding to 2:4 fb1 of integrated luminosity. We reconstruct the currently largest samples of the decay modes 0b ! cð2595Þþ (with cð2595Þ þ ! þc þ),0b ! cð2625Þþ (with cð2625Þ þ ! þ c þ), 0 b ! cð2455Þþþ (with cð2455Þþþ!þc þ), and 0b ! cð2455Þ0þ (with cð2455Þ0 ! þc ) and measure the branching fractions relative to the 0b!þc  branching fraction. We measure the ratio Bð0b !þ c þÞ=Bð0b !þc Þ ¼3:040:33ðstatÞþ0:70 0:55ðsystÞ which is used to derive Bð0b!þc þÞ¼ð26:8þ11:9 11:2Þ103.
