Book Description
This thesis describes a measurement of the lifetime of the B± c meson in an exclusive decay channel B± c 2!J/ [psi] [pi]±, where the J/[psi] decays as J/[psi] 2![mu]+[mu]- 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, [tau] = 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.

Book Description
The neutral B meson lifetime has been measured with the data collected by the BABAR detector at the PEP-II storage ring during the year 2000 for a total integrated luminosity of 20.3 fb[sup -1]. The B[sup 0][yields] D*[sup -][pi][sup+] decays have been selected with a partial reconstruction method in which only the fast pion from the B[sup 0] decay and the slow pion from D*[sup -][yields][bar D][sup 0][pi][sup -] are reconstructed. The B[sup 0] lifetime has been measured to be 1.510[+-] 0.040[+-] 0.038 ps with a sample of 6971[+-] 241 reconstructed signal events.

Book Description
This thesis describes a measurement of the average proper decay time of the B±c mesons, the ground state of bottom and charm quark bound states. The lifetime measurement is carried out in the decay modes B±c → J/[Psi] + e± + X and B±c → J/[Psi] + [mu]± + X, where the J/[Psi] decays as J/[Psi] → [mu]+[mu]- and the X are unmeasured particles such as ve or v[mu]. The data are collect by the CDF II detector which measures the properties of particles created in √s = 1.96 TeV p$\bar{p}$ collisions delivered by the Fermilab Tevatron. This measurement uses ~ 1 fb-1 of integrated luminosity. The measured average proper decay time of B±c mesons, [tau] = 0.475-0.049+0.053(stat.) ± 0.018(syst.) ps, is competitive with the most precise measurements in the world and confirms previous measurements and theoretical predictions.

Book Description
The authors present a measurement of the B{sub c} meson lifetime in the semileptonic decay mode B{sub c}+ → J/?e+?{sub e} using the CDF II detector at the Fermilab Tevatron Collider. From a sample of about 360 pb−1 of p{bar p} collisions at √s = 1.96 TeV, they reconstruct J/?e+ pairs with invariant mass in the kinematically allowed range 4
