Search 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 de...
