The authors present a search for B decays to charmless final states involving charged or neutral a[sub 0] mesons. The data sample corresponds to 89 million B[bar B] pairs collected with the BABAR detector operating at the PEP-II asymmetric-energy B Factory at SLAC. They find no significant signals and determine the following 90% C.L. upper limits: [Beta](B[sup 0] [yields] a[sub 0][sup -] [pi][sup +])

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.

The authors present results for measurement of the decays to charmless final states of B{sup 0} meson to {eta}K{sup 0}, {eta}{omega}, a{sub 1}{sup +}(1260){pi}{sup -} with a{sub 1}{sup +}(1260) {yields} {pi}{sup +}{pi}{sup +}{pi}{sup -}, and of B{sup +} to {eta}{rho}{sup +}, {eta}{prime}{pi}{sup +}. Analyses are based on data taken with the BABAR detector at the PEP-II asymmetric e{sup +}e{sup -} collider at SLAC.

The authors present measurements of branching fractions and CP-violating asymmetries in decays of B mesons to two-body final states containing a K[sup 0]. The results are based on a data sample of approximately 88 million [Upsilon](4S) [yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.

We have studied two-body charmless hadronic decays of B mesons into the final states[pi][pi], K[pi], and KK. Using 3.3 million B[bar B] pairs collected with the CLEO-II detector, we have made the first observation of the decays B[sup 0][yields] K[sup+][pi][sup -], B[sup+][yields] K[sup 0][pi][sup+], and the sum of B[sup+][yields][pi][sup+][pi][sup 0] and B[sup+][yields] K[sup+][pi][sup 0] decays (an average over charge-conjugate states is always implied). We place upper limits on branching fractions for the remaining decay modes.

This comprehensive work thoroughly introduces and reviews the set of results from Belle and BaBar - after more than two decades of independent and complementary work - all the way from the detectors and the analysis tools used, up to the physics results, and the interpretation of these results. The world’s two giant B Factory collaborations, Belle at KEK and BaBar at SLAC, have successfully completed their main mission to discover and quantify CP violation in the decays of B mesons. CP violation is a necessary requirement to distinguish unambiguously between matter and antimatter. The shared primary objective of the two B Factory experiments was to determine the shape of the so-called unitarity triangle, an abstract triangle representing interactions of quarks, the elementary constituents of matter. The area of the triangle is a measure of the amount of CP violation associated with the weak force. Many other measurements have been performed by the B Factories and are also discussed in this work.
