Lay summary
The Institute for Particle Physics (IPP) of ETH Zurich is one of the leading Institutes participating in the Compact Muon Solenoid (CMS) experiment at CERN's Large Hadron Collider (LHC). The design concept of the CMS experiment guarantees full exploitation of the physics potential offered by the LHC, which will provide proton-proton collisions at unprecedented centre-of-mass energies. CMS has thus a unique prospective for important discoveries in Particle Physics for the next decade. Two of the most important detector systems of the CMS experiment are the high precision Electromagnetic Calorimeter (ECAL), and the muon spectrometer. These systems are crucial for a large spectrum of measurements and their good performance is essential for the success of the CMS experiment. From the very beginning the IPP had major responsibility of scientific, technical and managerial nature for this ECAL subdetector. In particular, we carry the project leadership for the development, construction and operation of the Detector Control System (DCS) of ECAL. This project is realized in collaboration with scientists from the VINCA Institute and the Faculty of Physics of the University of Belgrade (Serbia). Similarly, Hungarian Institutes from Budapest and Debrecen have taken important responsibilities for the alignment system of the muon spectrometer. This proposal for a Joint Research Project (JRP) is intended to strengthen the already existing and very successful collaboration with our colleagues from Serbia. At the same time, we would like to extend this JRP to our colleagues from the Hungarian institutes and thus form a strong and competitive cluster of institutes within the large CMS collaboration. The objectives and expected results of the proposed JRP can be summarized as follows:?- Allow for prolonged stays of members from the Serbian and Hungarian research teams at CERN in order to carry out the following research activities:?o Operation and maintenance of the CMS ECAL safety system and the muon alignment system?o Participation in the final commissioning of the CMS detector and the start-up physics run?o Setting up and participation in physics analyses of LHC data, which concentrate on the exploitation of the excellent capabilities of the CMS sub-detectors. ?o Support of the data analysis activities in terms of theoretical contributions. ?- These activities should result in?o Highly efficient and safe operation of the CMS ECAL and precise muon track reconstruction thanks to an optimally aligned muon system?o An in-depth understanding of the first CMS data?o First Physics results from the analyses of the data collected during the initial years of LHC running.
