TLDR
In this article, a search for the decay of the charmed meson /ital D/sup 0/r arrow/bar K/sup +/e/sup /minus/3/ is presented, based on data collected at the /psi/(3770) resonance with the Mark III detector at the SLAC storage ring SPEAR.Abstract:
A search for the decay of the charmed meson /ital D//sup 0//r arrow//bar K//sup 0/e/sup +/e/sup /minus// is presented, based on data collected at the /psi/(3770) resonance with the Mark III detector at the SLAC storage ring SPEAR. No evidence for this process is found, resulting in an upper limit on the decay branching ratio of 1.7/times/10/sup /minus/3/ at the 90% confidence level.read more

TL;DR: In this paper, a search for charm hadron decays into two muons plus one or more hadrons has been carried out using a hybrid emulsion spectrometer, which is sensitive to modes with missing neutrals, e.g. π0μ+μ− and ϱ±μ+m−, as well as to constrained modes having visible invariant masses equal to those of charm states.
