Book Description
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.

Book Description
Using 1.3 fb-̂1 of data from p-pbar collisions at sqrt{s}=1.96 TeV collected with the CDF II detector at the Fermilab Tevatron, we have measured the relative branching ratio BR(B-̂ -> D0̂ K-̂)/BR(B-̂ -> D0̂ pi-̂) and its charge conjugate in the D0̂ flavor decay mode D0̂_f -> K-̂pi+̂ and the CP-even decay modes D0̂ -> K-̂K+̂ and D0̂ -> pi-̂pi+̂. From these measurements, we derive: R = (7.99 +- 0.33(stat.) +- 0.38(sys.)) %, R_{CP+} = 1.15 +- 0.17(stat.) +- 0.02(sys.), A_{CP+} = 0.10 +- 0.15(stat.) +- 0.02(sys.). These values are consistent with Standard Model expectations.

Book Description
We present a measurement of the absolute branching fraction for D[sup 0][yields] K[sup -][pi][sup+] using the reconstruction of the decay chain[bar B][yields] D*[sup+]X[ell][sup -][bar[nu]], D*[sup+][yields] D[sup 0][pi][sup+] where only the lepton and the low-momentum pion from the D*[sup+] are detected. With data collected by the CLEO II detector at the Cornell Electron Storage Ring, we have determined Br(D[sup 0][yields] K[sup -][pi][sup+])=[3.81[+-] 0.15(stat.)[+-] 0.16(syst.)]%.

Book Description
We present the measurement of the ratios of branching fractions B... to B..., and B... to B... We analyze data taken with the CDF II detector that corresponds to an integrated luminosity of 355 pb - 1 in pp collisions at ... TeV at the Fermilab Tevatron. Using a novel displaced track trigger we reconstruct 494 ± 28 B... decays, 8098 ± 114 B... decays, 159 ± 17 B... decays, and 3288 ± 76 B... decays. Using the world average value of the ... production ratio fs/fd = 0.259 ± 0.038, we determine the ratios of branching fractions ... where the uncertainties labeled BR and PR refer to the uncertainty on the D meson branching fractions and the production ratio fs/fd, respectively.
