Observation of a significant excess of pi(0)pi(0) events in B meson decays

Abstract:
Several 46±13±3 B0→π0π0 events with a significance of 4.2 standard deviations including systematic uncertainties were observed. A branching fraction Β(beta;0→π0π0)=(2.1±0 .6±0.3)X10-6 was measured. The systematic uncertainties from PDF variations and efficiency were combined in quadrature.
