چکیده
The decay mode Bs → ψK ∗ is suggested as a very good way to measure the Bs mixing parameter xs. These decays can be gathered using a ψ → l l trigger. This final state has a well resolved four track decay vertex, useful for good time resolution and background rejection.

متن کاملCLEO III, A Dectector To Measure Rare B Decays and CP Violation
The symmetric ee collider CESR is undergoing a series of upgrades allowing for luminosities in excess of 2×10cms. The most important goals of the upgrade are precision measurement of standard model parameters Vcb, Vub, Vtd/Vts, fDs, and searching for CP violation and standard model violations in rare B decays. A new detector upgrade, called CLEO III, has started which includes a new silicon-wir...

متن کاملDirc, a New Type of Particle Identification System for BaBar
The Dirc, a new type of Cherenkov imaging device, has been selected as the primary particle identification system for the BaBar detector at the asymmetric B-factory, Pep-II. It is based on total internal reflection and uses long, rectangular bars made from synthetic fused silica as Cherenkov radiators and light guides. In this paper, the principles of the Dirc ring imaging Cherenkov technique a...
