Electroweak model-independent tests for SU(3) symmetry in hadronic B decays -: art. no. 114015

We study the effects of new physics beyond the standard model an SU(3) symmetry in charmless hadronic two body B decays. It is found that several equalities for some of the decay amplitudes if small annihilation contributions an neglected, such as A(B-d(B-u)--> pi (+)pi (-),pi K-+(-)(pi (-) (K) over bar (0))) = A(B-s -->K(+)pi (-),K-K+(K-0(K) over bar (0))), A(B-d--> pi (+)rho (-), pi (-)rho (+),K(-)rho (+),pi K+*(-)) = A(B-s-->K(+)rho (-),pi K-*(+),K-K*(+), K+K*(-)), A(B-d(B-u)--> rho (+)rho (-),rho K+*(-)(rho (-)(K) over bar*(0))) = A(B-s-->K*(+)rho (-),K*K-*(+)(K*(0)(K) over bar*(0))), predicted by SU(3) symmetry in the SM are not affected by new physics. These relations provide important electroweak model independent tests for SU(3) symmetry in B decays. We also discuss how the assumption of the smallness of annihilation contributions can be tested experimentally.
