Fermilab E791 Collaboration: D. J. Summers (1) ((1) University of, Mississippi-Oxford)
TL;DR
This paper reports new limits on rare and forbidden D0 charm meson decays to leptons and mesons, significantly improving sensitivity for many decay modes, including some with no prior measurements.
Contribution
It provides the first published limits for 18 decay modes and enhances sensitivity for several others, advancing the search for rare charm decays.
Findings
Limits at the 10^-4 level for various decay modes
First published results for 18 decay channels
Improved sensitivity over previous experiments
Abstract
Limits at the 10**-4 level are reported for rare and forbidden decays of the D0 charm meson to a pair of leptons and either a vector meson or two pseudoscalar mesons. Of these searches, 18 are investigations of decays without previous published results; several others have significantly improved sensitivity over previous results.
