### Measurement of the branching fraction B(B-u(+)-&gt;J/psi pi(+)) and search for B-c(+)-&gt;J/psi pi(+)

Abstract:

We report on a measurement of the branching fraction of the Cabibbo-suppressed decay Bu +→J/ψπ+ , where J/ψ→μ+μ-. The data were collected by the Collider Detector at Fermilab during 1992-1995 and correspond to an integrated luminosity of 110 pb-1 in p̄p collisions at √s = 1.8 TeV. A signal of 289 +10 events is observed and we determine the ratio of branching fractions B(Bu +→J/ψπ+)/B(Bu +→J/ψK+) to be [5.0-1.7 +1.9(stat) ± 0.1(syst)]%. Using the world average value for B(Bu +→J/ψK+), we calcu...
