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
This work is the result of the researchers carried out during a three years Ph. D. period in the BABAR experiment. The first chapter consists in an introduction to the theoretical aspects of the D° meson lifetime determination and CP violation parameters, as well as an overview of the CP violation in the B sector, which is the main topic of the experiment. The description of the experimental apparatus follows with particular attention to the Silicon Vertex Tracker detector, the most critical detector for the determination of decay vertices and thus of lifetimes and time dependent CP violation asymmetries. In the fourth chapter the operation and running of the vertex detector is described, as a result from the experience as Operation Manager of the SVT, with particular attention to the safety of the device and the data quality assurance. The last chapter is dedicated to the determination of the D° meson lifetime with the BABAR detector, which is the main data analysis carried out by the candidate. The analysis is characterized by the selection of an extremely pure sample of D° mesons for which the decay flight length and proper time is reconstructed. The description of the unbinned maximum likelihood fit follows, as well as the discussion of the possible sources of systematic uncertainties. In the appendix is also presented a preliminary study of a possible development regarding the determination of mixing and CP violation parameters for the D° meson.
