1) ALICE experiment at LHC (CERN): the main goal of the ALICE
experiment is to study of ultrarelativistic heavy ion collisions
(Pb-Pb) up to a center-of-mass energy of 5.5 TeV per incident
nucleon pair. The constituents of the nucleon, in extreme
conditions of energy density and temperature should form a
particular state of matter, the so-called Quark-Gluon Plasma, where
partons are expected to be deconfined. 2) CMS experiment at LHC
(CERN): the physics programme of the experiment is focussed
on the study of proton-proton interactions up to a center-of-mass
energy of 14 TeV. The main research items are the search for the
Higgs Boson and the search of signals from supersymmetric
particles. 3) OPAL experiment at LEP (CERN): the
experiment has studied electron-positron collisions at the
center-of-mass energies close to the Z Boson mass and above the WW
pair production threshold, up to 209 GeV. Main physics
results include precision measurement of the electroweak
parameters, the study of the strong interaction and
constraints on the production of physics beyond the Standard Model.
