ResumoAbstract We have investigated electron production in 4.0 GeV/ c π + pinteractions. Limits to direct electron pair production are measured and an example of ϱ 0 or ω 0 decay to e + e − is observed. The ratio of the number of singly produced electrons to the total number of charged pions is less than 6 × 10 -5 (at the 95% confidence level).
