CMS

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
  2001. Important results have been obtained from
  the RD 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
