Search for the Flavor-Changing Neutral-Current Decays D+→π+μ+μ− and D+→π+e+e−

Year: 1996
Type: article
Abstract: We report the results of a search for the flavor-changing neutral-current decays ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ and ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{e}^{+}{e}^{\ensuremath{-}}$ in data from Fermilab charm hadroproduction experiment E791. No signal above background is found, and we obtain upper limits on branching fractions, $B({D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})<1.8\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ and $B({D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{e}^{+}{e}^{\ensuremath{-}})<6.6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$, at the 90% confidence level.
