A measurement of the decay amplitudes in B→ J/ψK* channels was presented using 20.7 fb-1 of data collected at the γ(4S) resonance. The effect of S-wave in the K* region was estimated by including a scalar term in the total amplitude. Monte Carlo simulation was also used to estimate uncertainities due to the assumed form for the mSearch for the decay B0 → γγ

A limit on the branching fraction for the decay Bo→γγ was presented using data collected at the γ(4S) resonance at the PEP-II asymmetric energy collider. The energy resolution was measured with a radioactive source at low energy and with electrons from Bhabha scattering at high energy. The energy deposits were reconstructed by grouping adjacent crystals with energy deposits greater than 1 MeV into clusters.Measurements of the branching fractions of exclusive charmless B meson decays with η′ or ω mesons
