SummarySummaryRare D semileptonic modes: De, ’e, e,
have been studied using 281/pb of data at the (3770)
D e is observed for the first time in two submodes: and +-0
No signal candidates are observed for D ’e and D e. Upper limits are set for these modes.
CLEO-c is going to collect a much larger sample at the (3770). This sample will improve statistical precision of existing measurements and allow observations of new modes.
