Abstract:

The performance of a prototype Ring Imaging Cherenkov Detector is studied using a charged particle beam. The detector performance, using CF4 and air as radiators, is described. Cherenkov angle precision and photoelectron yield using hybrid photo-diodes and multi-anode PMTs agree with simulations and are assessed in terms of the requirements of the LHCb experiment.

Abstract:

We report on a search for the decay B⁺→D^*+Ks⁰ and its charge conjugate with the CLEO detector at the Cornell Electron Storage Ring (CESR). No candidates are found in 9.10 fb^-1 of data. The background is estimated to be 0.29±0.05 leading to an upper limit B(B⁺→D^*+K⁰) = 9.5×10^-5 (90% confidence level). ©2001 The American Physical Society.

51�� of dimuon production in photon-photon collisions and measurement of QED photon structure functions at LEP

European Physical Journal C 19:1 (2001) 15-28

Authors:

Abstract:

Muon pair production in the process e⁺e^- → e⁺e^- μ⁺μ^- is studied using the data taken at LEP1 (√s ≃ mz) with the DELPHI detector during the years 1992-1995. The corresponding integrated luminosity is 138.5 pb^-1. The QED predictions have been tested over the whole Q² range accessible at LEP1 (from several GeV²/c⁴ to several hundred GeV²/c⁴) by comparing experimental distributions with distributions resulting from Monte Carlo simulations using various generators. Selected events are used to extract the leptonic photon structure function F^γ2. Azimuthal correlations are used to obtain information on additional structure functions, F^γA and F^γB, which originate from interference terms of the scattering amplitudes. The measured ratios F^γA/F^γ2 and Fγ��/F^γ2 are significantly different from zero and consistent with QED predictions.
