Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2004. === Includes bibliographical references (p. 201-209). === In this dissertation, we present the results of the average lifetime measurements in ..., ..., and ... decays, as well as the results of a time-dependent angular analysis of ... and ... decays. The time-dependent angular analysis of ... allows the extraction of separate lifetimes for the mass eigenstates, ... and ..., in the ... system. The two lifetimes are combined to extract the width difference, ..., between the two eigenstates. This quantity is extremely useful for over-constraining the Unitarity Triangle and thereby inferring if CP violation in the quark sector is entirely explained within the Standard Model. From ... of data collected by CDF up to February 13, 2004, we obtain a wealth of results, most importantly: ... Several of the results obtained here are currently the best of their kind, and in some cases they are unique measurements. We devote special attention to these, in particular ... === by Konstantin Anikeev. === Ph.D.
