Abstract

The search for B0 decays to charmless isoscalar meson pairs was carried out. The B0→φφ decay is define as a pure penguin annihilation process with an expected branching fraction of order 19 in the standard model. It was found that the branching functions or limits bear on the accuracy with CP-violating asymmetry measurements. The charged particles from e+e- interactions were detected and their momenta was measured using a combination of a vertex tracker.
