Lay summary
HCb is an experiment designed for precise measurements of CP violation and rare B decays at the Large Hadron Collider (LHC) at CERN. Its physics aims are to elucidate the flavour structure in the quark sector, and hopefully observe signals from New Physics. LHCb is expected to be ready to record LHC's first (low-energy) collisions in 2007, and deploy its full physics program in 2008 from the start of the high-energy operation of LHC. The particle physics group in Lausanne, now at EPFL's Laboratory for High-Energy Physics (LPHE), has been participating in LHCb since the beginning of the project in 1995. A group from the University of Zurich has joined the LHCb collaboration in 1999. Members of LPHE play important roles in the leadership of the LHCb experiment. Our main responsibilities and activities are: - Development, construction, and commissioning of the readout boards "TELL1" and of the electronics for LHCb's silicon vertex detector "VELO". - Development, construction, and commissioning of the silicon "Inner Tracker" detector. - Participation in Monte Carlo studies to develop trigger algorithms, optimize physics performance and prepare physics analysis. Our objectives for the forthcoming period (April 2007-March 2008) are: - Commissioning of the TELL1 boards, VELO readout and VELO power supplies, without and with LHC beams, and development of successive versions of the TELL1 firmware until the 2008 physics data-taking. - Installation and commissioning of the Inner Tracker, without and with LHC beams, and detector calibration and software alignment. - Participation in further development of the trigger algorithms and in the preparation for real data analysis.
