In the last decade the CLEO II collaboration, using the CESR e+e− storage ring, has accumulated nearly 15fb−1 of luminosity. in the energy region around 10.5 GeV, corresponding to the production of more than 3·107 charmed particles (apart from d

CLEO's large sample of ♥(4S) decays has yielded measurements of the various exclusive semileptonic decays: ( B 0 , B − ) → (D + , D ∗ + )l \ gn l and (D 0 , D ∗ 0 )l \ gn l . These imply the ratio of the charged and neutral lifetimes to be

Using almost 5fb −1 of e+e− data accumulated at the CESR collider in the energy region around 10.5 GeV, the CLEO II collaboration has found evidence for several narrow excitations of the Ξc. Two of these are seen in the modes Ξ c + γ and Ξ c

We discuss the design and performance of a threshold Cerenkov counter for identification of charged hadrons. The radiator is pressurized gas, which is contained in thin-walled cylindrical modules. A mirror system of novel design transports Cerenkov p

B-factory designers and prospective users have learned that the viability of such facilities is crucially dependent upon control of machine-related backgrounds in the interaction region (IR). Photons from synchrotron radiation (SR), and the debris th
