Decays ofBmesons to two pseudoscalars in broken SU(3) symmetry

Abstract

The decays of B mesons to two-body hadronic final states are analyzed within the context of broken flavor SU(3) symmetry, extending a previous analysis involving pairs of light pseudoscalars to decays involving one or two charmed quarks in the final state. A systematic program is described for learning information from decay rates regarding (i) SU(3)-violating contributions, (ii) the magnitude of exchange and annihilation diagrams (effects involving the spectator quark), and (iii) strong final-state interactions. The implication of SU(3)-breaking effects for the extraction of weak phases is also examined. The present status of data on these questions is reviewed and suggestions for further experimental study are made.

“…These non leptonic decays have been proposed long ago [6,7,8,9,10,11,12,13,14,15,16,17,18] as a method for the extraction of the γ angle. By this strategy one relates the data to a theoretical amplitude given as a sum of Tree and Penguin short distance contributions, whose relative weak phase is indeed γ.…”

“…Approximations typically involve arguments about different contractions of the involved operators which are commonly described in terms of topological amplitudes [28][29][30][31], which can, however, be expressed in terms of SU(3) MEs [26]. We therefore translate the derived SU(3) amplitudes into this language, using the topological amplitudes introduced in Ref.…”
