B Decays

This 2nd edition is an extensive update of "B Decays". The revisions are necessary because of the extensive amount of new data and new theoretical ideas. This book reviews what is known about b-quark decays and also looks at what can be learned in the future.

The importance of this research area is increasing, as evidenced by the approval of the luminosity upgrade for CESR and the asymmetric B factories at SLAC and KEK, and the possibility of experiments at hadron colliders.

The key experimental observations made thus far, measurement of the lifetimes of the different B species, B⁰-B⁰ mixing, the discovery of "Penguin" mediated decays, and the extraction of the CKM matrix elements Vub and Vcb from semileptonic decays, as well as more mundane results, are described in great detail by the experimentalists who have been closely involved with making the measurements. Theoretical progress in understanding b-quark decays using HQET and lattice gauge techniques are described by theorists who have developed and used these techniques.

Synthesizing the experimental and theoretical information, several articles discuss the implications for the "Standard Model" and how further tests can be done using measurements of CP violation in the B system.
