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.
