Description
Evidence for the rare decay π0→e+e- has been obtained in an experiment which measured the invariant mass spectrum of e+e- pairs produced by 300-MeV/c π- mesons interacting in a liquid-hydrogen target. The branching ratio is (1.8 +- 0.6) x 10-7, about four times larger than the unitarity lower limit
