The B^- -> phi phi K^- decay rate with phi phi invariant mass below charm treshold
We investigate the decay mechanism in the B^- -> phi phi K^- decay with the
phi phi invariant mass below the charm threshold and in the neighborhood of the
eta_c invariant mass region. Our approach is based on the use of factorization
model and the knowledge of matrix elements of the weak currents. For the B
meson weak transition we apply form factor formalism, while for the light
mesons we use effective weak and strong Lagrangians. We find that the dominant
contributions to the branching ratio come from the eta, eta' and eta(1490) pole
terms of the penguin operators in the decay chains B^- -> eta (eta', eta(1490))
K^- -> phi phi K^-. Our prediction for the branching ratio is in agreement with
the Belle's result.Comment: 14 pages, 4 figures, 2 table
