| Abstract | We investigate the decay mechanism in the B − → φφK − decay below charm threshold and in the neighborhood of the η c invariant mass region. Our approach is based on the use of factorization 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 a combination of the matrix elements of the tree and the penguin operators. Our result for the branching ratio and Dalitz plot are in good agreement with the Belle measurement. |
