Relative branching fractions of B{sub d, s}{sup 0} {yields} h{sup +}h'{sup -} decays (where h, h' = K or {pi}) and the direct Cp asymmetry A{sub CP} in the B{sub d}{sup 0} {yields} K{sup +}{pi}{sup -} mode are measured with 179 {+-} 11 pb {sup -1} of data collected using the CDF II detector at the Fermilab Tevatron p{bar p} collider. The first branching-fraction measurement of a B{sub s}{sup 0} meson to two pseudoscalars, {Beta}(B{sub s}{sup 0} {yields} K{sup +} K{sup -}), and a search for the baryon mode {Lambda}{sub b}{sup 0} {yields} p{sup +} h{sup -} are also presented, in addition to branching-fraction limits on the rare channels B{sub s}{sup 0} {yields} K{sup +} {pi}{sup -}, B{sub d}{sup 0} {yields} K{sup +}K{sup -}, and B{sub s}{sup 0} {yields} {pi}{sup +}{pi}{sup -}.

This book highlights two essential analyses of data collected during the LHCb experiment, based on the Large Hadron Collider at CERN. The first comprises the first observation and studies of matter-antimatter asymmetries in two three-body b-baryon decays, paving the way for more precise measurements of the relatively unknown decay properties of b-baryon decays. The second is an analysis of a charged B meson decay to three charged pions, where previously large matter-antimatter asymmetries were observed in a model-independent analysis. Here a model of the decay amplitude is constructed using the unitarity-conserving ‘K-matrix’ model for the scalar contributions, so as to gain an understanding of how the previously observed matter-antimatter asymmetries arise; further, the model’s construction yields the most precise and comprehensive study of this decay mode to date.

The authors present preliminary measurements of the branching fraction and the CP-violating charge asymmetry in the B[sup +] --> K[sup 0][pi][sup +] decay, and a preliminary measurement of the branching fraction of the B[sup 0] --> K[sup 0][bar K][sup 0] decay. No evidence of direct CP violation in the B[sup +] --> K[sup 0][pi][sup +] mode is observed. The B[sup 0] --> K[sup 0][bar K][sup 0] measurement constitutes the first observation of this decay channel: the probability of obtaining the result assuming the null-signal hypothesis is 3.4 x 10[sup -6]. The authors have also searched for the B[sup +] --> [bar K][sup 0]K[sup +] decay and set an upper limit on its branching fraction at 2.35 x 10[sup -6] at the 90% C.L. The branching-fraction measurements reported here are consistent with previous measurements of the same quantities, but are extracted from a data sample larger by a factor of 2.6.

The authors present preliminary measurements of the branching fraction and the CP-violating charge asymmetry in the B --> K°?+ decay, and a preliminary measurement of the branching fraction of the B° --> K°{bar K}° decay. No evidence of direct CP violation in the B+ --> K°?+ mode is observed. The B° --> K°{bar K}° measurement constitutes the first observation of this decay channel: the probability of obtaining the result assuming the null-signal hypothesis is 3.4 x 10−6. The authors have also searched for the B+ --> {bar K}°K+ decay and set an upper limit on its branching fraction at 2.35 x 10−6 at the 90% C.L. The branching-fraction measurements reported here are consistent with previous measurements of the same quantities, but are extracted from a data sample larger by a factor of 2.6.

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.
