abstract = "We report the results of a search for the flavor-changing neutral-current decays D+→ π+μ+ μ− and D+→ π+e+ e− in data from Fermilab charm hadroproduction experiment E791. No signal above background is found, and we obtain upper limits on branching fractions, B(D+→ π+μ+ μ−) < 1.8 ×10−5 and B(D+→ π+e+ e−) < 6.6 × 10−5, at the 90% confidence level.",
