1. CMS Goal of the experiment
To explore the physics of p-p collisions at 14 TeV center-of-mass-energy of LHC.
The main goal of CMS will be the search and study of the Higgs boson and of the super-symmetric
partners of the known particles. The scientific program includes also detailed studies of the top quark and
precision measurements of CP violation parameters in the b-system. The physics of heavy ion collisions to identify the signature and study the properties of quark-gluon plasma will also be addressed.
Physics achievements in 2001
The experiment is still in construction, therefore no physics result has been achieved in Important results have been obtained from the R&D activity carried on for all the sub-systems of the experiment, including computing.
INFN contribution to the experiment in terms of manpower and financial support
INFN researchers are involved in the following sub-detectors: Solenoidal Magnet, Tracker, Electromagnetic Calorimeter, Muon System and Computing. The total number of physicists and engineers working in CMS in 2001 is 221. They come from 12 INFN Laboratories and account for about 15% of the total number of CMS collaborators. Technicians are not included in these figures.
The INFN financial support for CMS deliverables amounts to about 55 MCHF over an estimated total cost of the experiment around 466 MCHF.
Funding foreseen in the 2002 Budget: 8141 kEuro
