STUDY OF A FAST TRIGGER SYSTEM ON BEAUTY EVENTS AT FIXED TARGET AND COLLIDERS

One of the most challenging issues in the physics of the next few years is the study of the b-quark, via the detection of B-mesons and hadrons. The physical interest ranges from the measurement of the parameters in the Kobayashi-Maskawa matrix to that of CP violation in the neutral B-B system. Also, solving the problem of triggering and detecting B-mesons is a most effective way of approaching the problem of the detection of higher-mass heavy flavours. We describe here an R&D program, planned for the next two years, aimed at the study of a fast trigger system on beauty events, for both fixed target and collider experiments. © 1990.
