Measurement of the $$B_c^{\pm}$$ meson lifetime using $$B_c^{\pm} \to J/\psi~\pi^{\pm}$$ decays
Abstract
This thesis describes a measurement of the lifetime of the B± c meson in an exclusive decay channel B± c → J/ ψ π±, where the J/ψ decays as J/ψ → μ+μ- . 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 B± c meson lifetime in a hadronic channel and the measured lifetime, τ = 0.449 +0.054 -0.048(stat:) ± 0.019(syst:) ps, is in good agreement with previous results obtained from semileptonic decay channel and confirms previous measurements and theoretical predictions.
