Lay summary
LHCb is an experiment designed for precise measurements of CP violation and rare B decays at the LHC collider at CERN. LHCb's main physics aims are to elucidate the flavour structure in the quark sector, and hopefully observe signals from New Physics.Our particle physics group in Lausanne, at EPFL's Laboratory for High-Energy Physics (LPHE), has worked on LHCb since the beginning of the project in 1995 and plays important roles in the leadership of the experiment.During the forthcoming funding period we will commission and calibrate all hardware devices under our responsibility (TELL1 boards, VELO readout chain, and all aspects of the Inner Tracker), without and with LHC beams, so that we can use them as soon as possible, together with the rest of the LHCb detector, for the first physics studies. Our financial objectives in this period are: (1) Together with University of Zurich (prof. U. Straumann), fulfill the Swiss commitments towards the construction of the LHCb detector, which have been defined several years ago in a Memorandum of Understanding between all participating countries and CERN.(2) Together with other institutes involved in the VELO project, and with the help of the whole collaboration, gather the resources necessary for the construction of a complete set of spare VELO modules, needed to replace the existing VELO modules in case of a severe beam accident, or anyway after a few years of operation in the high-radiation environment of the LHC.We request 400 kCHF from FORCE for the above two items. Additional funding for the LHCb project (salaries, consumables, and travel expenses) is asked for in our SNSF request no. 199968.

Abstract

LHCb is an experiment designed for precise measurements of CP violation and rare B decays at the LHC collider at CERN. Its main 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 collisions in 2008, and deploy its full physics program as soon as the LHC reaches a luminosity of 2 10^32 cm-2 s-1.The particle physics group in Lausanne, now at EPFL's Laboratory forHigh-Energy Physics (LPHE), has worked on LHCb since the beginningof the project in 1995 and plays important roles in the leadershipof the experiment.The main construction responsibilities of the group are: - Development and construction of the common readout boards TELL1 and of the electronics for LHCb's silicon vertex detector.- Development and construction of the silicon Inner Tracker detector, in collaboration with other institutes (in particular University of Zurich)involved in LHCb's Silicon Tracker project.The objectives for the forthcoming 2-year funding period 2008-2010 are:- Commissioning of the hardware devices under our responsibility (TELL1 boards and firmware, VELO power supplies and readout chain, and all aspects of the Inner Tracker), without and with LHC beams, such as to render them fully operational as soon as possible.- Calibration, performance monitoring and software alignment of the Inner Tracker.- Participation in the first data analysis and physics measurements.- In addition, considering possible future involvement in the LHCb upgrade (and also in preparation for the next experiment), start of new R\&D activities for an upgraded TELL1 board and in the area of fibre tracking.
