CMS

• Goal of the experiment
• CMS is a general purpose apparatus for
  LHC designed to study the physics of p-p
  collisions at the center-of-mass energy of 14
  TeV. The main goal of the experiment is the
  search for the Higgs boson and for the
  super-symmetric partners of 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, and, in particular, the
  clear identification of a new state of matter as
  the quark-gluon plasma will also be addressed.
• Physics achievements in 2002
• The experiment is still in construction,
  therefore no physics result has been achieved in
  2002. Important results have been obtained from
  the RD activity carried on for all sub-detectors
  including computing. The main goal of this phase
  of the experiment is a successful commissioning
  of the main detector components.
• 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 2002 is 252. They
  come from 13 INFN Laboratories and account for
  about 16 of the total number of CMS
  collaborators. Technicians are not included in
  these figures.
• The INFN financial support to CMS deliverables
  amounts to about 63.9 MCHF over an estimated
  total cost of the experiment around 500 MCHF. The
  overall INFN financial support to CMS for the
  year 2002 is 8141KEuro, including travel expenses
  and consumables.
