Abstract
Experiments are now able to address detailed questions in charm decay by studying difficult decay modes that were inaccessible earlier. The important features of the two experiments discussed here, E-691 and NA-32, are high rates and silicon vertex detectors. The Fermilab photoproduction experiment E-691 used tagged photons of energy 80–230 GeV, and recorded 108 events from which 104 charm events were reconstructed. The beam for CERN hadroproduction experiment NA-32 was 230 GeV/c π-. The trigger selected events with a pK- or K+K- pair and led to a sample of 1200 reconstructed charm events in 20 decay modes.
