Abstract
We present a measurement of the B-c(+) meson lifetime in the decay mode B-c(+) -> J/psi e(+) nu(e) using the Collider Detector at Fermilab II detector at the Fermilab Tevatron Collider. From a sample of about 360 pb(-1) of pp collisions at root s = 1.96 TeV, we reconstruct J/psi e(+) pairs with invariant mass in the kinematically allowed range 4 < M-J/psi e < 6 GeV/c(2). A fit to the decay-length distribution of 238 signal events yields a measured B-c(+) meson lifetime of 0.463(-0.065)(+0.073) (stat) +/- 0.036 (syst) ps.
