FSI rescattering in B± decays via states with η, η′ ω and φ

New results going beyond those obtained from isospin and flavor symmetry and subject to clear experimental tests are obtained for effects of FSI in B+/- decays to charmless strange final states containing neutral flavor-mixed mesons like omega, phi, eta and eta'. The most general strong-interaction diagrams containing arbitrary numbers of quarks and gluons are included with the assumptions that any q (q) over bar pair created by gluons must be a flavor singlet, and that there are no hairpin diagrams in which a final meson contains a q (q) over bar pair from the same gluon vertex. The smallness of K(-)eta suggests that it might have a large CP violation. A sum rule is derived to test whether the large K(-)eta' requires the addition of an additional glueball or charm admixture. Further analysis from D-s decay systematics supports this picture of FSI and raises questions about charm admixture in the eta'. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
