The Argus Vertex Trigger

A fast second level trigger has been developed for the ARGUS experiment which recognizes tracks originating from the interaction region. The processor compares the hits in the ARGUS Micro Vertex Drift Chamber to 245760 masks stored in random access memories. The masks which are fully deened in three dimensions are able to reject tracks originating in the wall of the narrow beampipe of 10.5 mm r...

Recent Results from ARGUS

Some recent results are reported from the ARGUS experiment, operated at the e+estorage ring DORIS Il at DESY. In an updated analysis of semileptonic b u decays direct evidence for such transitions was obtained through reconstruction of a complete event. A study of the lepton energy spectra in +-+ E-UP and z+ P-I+ decays yielded a value for the Michel parameter which is in good agreement with a ...
