This biennial Review summarizes much of Particle Physics. Using data from previous
editions, plus 1600 new measurements from 550 papers, we list, evaluate, and average …

A review of the present understanding of η′ and η meson physics and these mesons as a
probe of gluon dynamics in low-energy QCD is presented. Recent highlights include the …

There exist many experimental indications that final-state interactions (FSIs) may play a
prominent role not only in charmful B decays but also in charmless B ones. We examine the …

We report a theoretical analysis of the exclusive nonleptonic decays of the B±and B 0
mesons into two light mesons, some of which have been measured recently by the CLEO …

A bound on the angle γ of the unitarity triangle is derived using experimental information on
the CP-averaged branching ratios for the rare decays B±→ π±K0 and B±→ π0K±. The …

Expressions for decay amplitudes of B¯ 0, B-, and B¯ s 0 mesons to two light pseudoscalar
or vector mesons, including isosinglet mesons η, η′, ω, ϕ, are obtained using soft collinear …

Two-body charmless nonleptonic decays of B u and B d mesons are studied within the
framework of generalized factorization in which the effective Wilson coefficients ci eff are …

The decays of B mesons to a pair of charmless pseudoscalar (P) mesons are analyzed
within a framework of flavor SU (3). Symmetry breaking is taken into account in tree (T) …

We point out new ways to search for charmless baryonic B decays and suggest that
enhanced baryon production is favored by reduced energy release on the baryon side. Thus …

We prove a general theorem about equal CP rate differences within pairs of U-spin related
charmless B and Bs decays. Large deviations from equalities would be evidence for new …
