Abstract

We report the result of a search for the rare decay B0→γγ using a combined dataset of 753×106 BB¯ pairs collected by the Belle experiment and 387×106 BB¯ pairs collected by the Belle II experiment from decays of the ϒ(4S) resonance produced in e+e− collisions. A simultaneous fit to the Belle and Belle II data sets yields 11.0−5.5+6.5 signal events, corresponding to a 2.5σ significance. We determine the branching fraction B(B0→γγ)=(3.7−1.8+2.2(stat)±0.5(syst))×10−8 and set a 90% credibility level upper limit of B(B0→γγ)<6.4×10−8.
