Measurement of the B-c(-) meson lifetime in the decay B-c(-) -> J/psi pi(-)
The lifetime of the Bc- meson is measured using 272 exclusive Bc-→J/ψ(→μ+μ-)π- decays reconstructed in data from proton-antiproton collisions corresponding to an integrated luminosity of 6.7 fb-1 recorded by the CDF II detector at the Fermilab Tevatron. The lifetime of the Bc- meson is measured to b...
