Search for the decay B0 →φγ

Research output: Contribution to journalArticlepeer-review

Abstract

We have searched for the decay B0→φγ using the full Belle data set of 772×106 BB pairs collected at the (4S) resonance with the Belle detector at the KEKB e+e- collider. No signal is observed, and we set an upper limit on the branching fraction of B(B0→φγ)<1.0×10-7 at the 90% confidence level. This is the most stringent limit on this decay mode to date.
