Abandoning Exact SU(3) in Coupled-Channel Final-State Interactions through Reggeon Exchange for $B\to \pi \pi ,K\bar{K}$

P. Lach

For weak decays $B_d^0\to \pi \pi$ and $K\bar{K}$ the effects of SU(3) breaking in coupled-channel final-state interaction effects are discussed in a Regge framework. It is shown that…
