Search for the Flavor-Changing Neutral-Current Decays $$D^+\to \pi^+ \mu^+ \mu^-$$ and $$D^+\to \pi^+ e^+ e^-$$
We report the results of a search for the flavor-changing neutral-current decays $$D^+\rightarrow \pi^+ \mu^+ \mu^-$$ and $$D^+\rightarrow \pi^+ e^+ e^-$$ in data from Fermilab charm hadroproduction experiment E791. No signal above background is found, and we obtain upper limits on branching fractions, $$B(D^+\rightarrow \pi^+ \mu^+ \mu^-) < 1.8 \times 10^{-5}$$ and $$B(D^+\rightarrow \pi^+ e^+ e^-) < 6.6 \times 10^{-5}$$, at the 90\% confidence level.
