Fermilab Experiment E831

FOCUS is a heavy-flavor photoproduction experiment located at the Wide Band Area of Fermilab. It is an upgraded version of its predecessor, E687.

      The experiment is collected data during the 1996-97 fixed target run, and is investigating several topics in charm physics including high precision studies of charm semileptonic decays, QCD studies using double charm events, a measurement of the absolute branching fraction for the D0 meson, a systematic investigation of charm baryons and their lifetimes, and searches for D0 mixing, CP violation, rare and forbidden decays, and fully leptonic decays of the D+. Based on experience with E687, FOCUS expects to fully reconstruct 106 charm particle decays.

mode charm decays have been reconstructed by
