The MEMPHYS project: A large scale water-Cherenkov detector in Europe
The feasibility of a next generation neutrino observatory in Europe is being considered within the LAGUNA design study. To accommodate giant neutrino detectors and shield them from cosmic rays, a new very large underground infrastructure is required. Seven potential candidate sites in different parts of Europe and at several distances from CERN are...
The proximity focusing Hybrid Photon Detector (HPD) concept is implemented to develop a single photon sensitive Electron Bombarded CMOS (EBCMOS). The first demonstrator has been produced by the collaboration between the EBCMOS group of IPNL, the CMOS sensor group of IPHC and the R&D department of PHOTONIS. The prototype characteristics (dark curren...
A cheap and practical alternative to plastic scintillating tracker for large surface detectors is developed. Large scale prototype was built and tested, showing high perfomance, good reliability and outstanding ease of production and handling. The worked out technology ensure low cost and high uniformity production of tracker modules, based on comm...
Searches for charginos, neutralinos and sleptons in e+ e collisions at center-of-mass energies of 161 and 172 GeV have been performed on DELPHI data, under the assumptions that R-Parity is not conserved and that the dominant R-Parity violating couplings involve only leptonic or only quark elds. Particular emphasis is given in decays involving, the ...
In this report we review the prospects for Higgs physics at LEP2. The theoretical aspects and the phenomenology of Higgs particles are discussed within the Standard Model (SM) and the Minimal Supersymmetric Standard Model (MSSM). The experimental search techniques are described and the discovery limits for Higgs bosons in the LEP2 energy range are ...
Review of prospects for discovery of new physics signals at LEP2. The areas covered include SUSY, exotic fermions, BESS models, leptoquarks, virtual effects and CP violating observables.
Previous studies of the physics potential of LEP2 indicated that with the design luminosity of 500 inverse picobarn one may get a direct measurement of the mass of the W-boson with a precision in the range 30 - 50 MeV. This report presents an updated evaluation of the estimated error on the mass of the W-boson based on recent simulation work and im...
Review of Monte Carlo event generators for signals of new particles at LEP2. The areas covered include SUSY, HIGGS and Leptoquarks.
