Abstract
We report the results of a search for the flavor-changing neutral-curr ent decays D+ --> pi(+)mu(+)mu(-) and D+ --> pi(+)e(+)e(-) in data fro m Fermilab charm hadroproduction experiment E791. No signal above back ground is found, and we obtain upper limits on branching fractions, B( D+-->pi(+)mu(+)mu(-)) < 1.8 x 10(-5) and B(D+-->pi(+)e(+)e(-)) < 6.6 X 10(-5), at the 90% confidence level.
