Heavy Flavors at the Cornell Electron Storage Ring

We use the CLEO detector at CESR to study the properties of thetau lepton and of particles containing the b and c quarks. These studies allow us to perform stringent tests of the standard model of particle physics. We are working on a silicon microstrip vertexdetector which will give 0.1 psec time resolution for particlelifetimes. This will significantly enhance the experiment'ssensitivity to new physics.
