Abstract
We report on a measured of the branching fraction of the Cabibbo-suppr essed decay B-u(+)-->J/psi pi(+), where J/psi-->mu(+)mu(-). The data w ere collected by the Collider Detector at Fermilab during 1992-1995 an d correspond to an integrated luminosity of 110 pb(-1) in (p) over til dep$ collisions at root s=1.8 TeV. A signal of 28(-9)(+10) events is o bserved and we demonstrate the ratio of branching fractions B(B-u(+)-- >J/psi pi)/B(B-u(+)-->J/psi K+) to be [5.0(-1.7)(+1.9) (stat)+/-0.1(sy st)]%. Using the world average value for B(B-u(+)-->J/psi K+), we calc ulate the branching fraction B(B-u(+)-->J/psi pi(+)) to be (5.0(-1.9)( +2.1))x10(-5). We also search for the decay B-c(+)-->J/psi pi(+) and r eport a 95% confidence level limit on sigma(B-c(+))B(B-c(+)-->J/psi pi (+)/sigma(B-u(+))B(B-u(+)-->J/psi K+) as a function of the B-c(+) life time.
