Measurement of the B[subscript c][superscript -] meson lifetime in the decay B[subscript c][superscript -] →J/ψπ[superscript -]

The lifetime of the B[subscript c][superscript -] meson is measured using 272 exclusive B[subscript c][superscript -]→J/ψ(→μ[superscript +]μ[superscript -])π[superscript -] decays reconstructed in data from proton-antiproton collisions corresponding to an integrated luminosity of 6.7  fb[superscript...

description The lifetime of the B[subscript c][superscript -] meson is measured using 272 exclusive B[subscript c][superscript -]→J/ψ(→μ[superscript +]μ[superscript -])π[superscript -] decays reconstructed in data from proton-antiproton collisions corresponding to an integrated luminosity of 6.7  fb[superscript -1] recorded by the CDF II detector at the Fermilab Tevatron. The lifetime of the B[subscript c][superscript -] meson is measured to be τ(B[subscript c][superscript -])=0.452±0.048(stat)±0.027(syst)  ps. This is the first measurement of the B[subscript c][superscript -] meson lifetime in a fully reconstructed hadronic channel, and it agrees with previous results and has comparable precision.
