Description
The lifetime of the $B_{c}^{-}$ meson is measured using the exclusive $B_{c}^{-} \rightarrow J/\psi~\pi^{-}$} decay with data from $p\overline{p}$ collisions with an integrated luminosity of 6.7~fb$^{-1}$ recorded by the CDF detector at the Fermilab Tevatron. This is the first measurement of the $B_{c}^{-}$ meson lifetime in a fully-reconstructed hadronic channel, and the result is in agreement with previous results. The lifetime of the $B_{c}^{-}$ meson is measured to be: $c\tau$(\bc) = 136~$\pm$~14(stat)~$\pm$~8(syst)~$\mu$m
