We report on the results of a search for fourteen flavor changing neutral current, lepton number violating, or lepton family number violating decays of the charmed meson D+ in the large charm sample recorded by the Fermilab photoproduction experiment E687. No evidence is seen for these rare and standard-model-forbidden decays, of the form D+ → h±l∓l+ (with h = π, K and l = e, μ); we determine 90% confidence level upper limits on their absolute branching fractions in the range (9-20) × 10-5.

Abstract

We report on the results of a search for fourteen flavor changing neutral current, lepton number violating, or lepton family number violating decays of the charmed meson D+ in the large charm sample recorded by the Fermilab photoproduction experiment E687. No evidence is seen for these rare and standard-model-forbidden decays, of the form D+ → h±l∓l+ (with h = π, K and l = e, μ); we determine 90% confidence level upper limits on their absolute branching fractions in the range (9-20) × 10-5.
