Search for B 0→π 0π 0 decay

We have searched for the charmless hadronic decay of B 0 mesons into two neutral pions. Using 9.13 fb -1 taken at the Y(45) with the CLEO detector, we obtain an improved upper limit for the branching fraction B(B 0 → π 0π 0)<5.7×10 -6 at the 90% confidence level. © 2002 The American Physical...
