Dissertation Abstract

"This thesis describes a measurement of the lifetime of the Bc meson in an exclusive decay
channel Bc to  J/psi pi. The measurement uses a data sample with
an integrated luminosity of 6.7 fb$^{-1}$ collected at CDF. This is the first
measurement of the Bc meson lifetime in a hadronic channel and the
measured lifetime, $\tau = 0.449~^{+0.054}_{-0.048}(stat.)~\pm~0.019(syst.)$~ps, is in good
agreement with previous results obtained from semileptonic decay channel and confirms
previous measurements and theoretical predictions."
