European Organization for Nuclear Research - CERN

The Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) is the one of four large experimental facilities. LHC program will address the fundamental questions in high energy particle physics, namely that of origin of the spontaneous symmetry breaking mechanism, testing grand unification models, search for supersymmetry (SUSY), new gauge bosons, etc.

The CMS detector is one of the largest international scientific collaborations in history. There are 2300 people working for CMS, 1940 of which are scientists and engineers. These people come from 179 institutes in 40 countries, spanning Europe, Asia, the Americas and Australia. The members from RUSSIA AND DUBNA MEMBER STATES (RDMS) created an organizational structure providing the necessary strength to take responsibility for the construction of detectors for CMS and appear as a single scientific body called RDMS CMS.
Institute for Nuclear Research as one of the RDMS CMS institutions plays an active role in CMS project. Main systems of electromagnetic calorimeter are developed and constructed by the INR members, including unique alveolar structures and vacuum phototriods. The researchers from Laboratory for physical processes modelling have investigated the possibility to search for lepton flavour violation processes using the CMS detector.

A Large Ion Collider Experiment at the LHC - project ALICE. An idea of possibility of quark-gluon plasma existance in nature attracted significant interes of scientific society and in late 1990-th a new generation experimental setup development has started for the ALICE experiment at European Center of Nuclear Research [CERN]. The Laboratory of Meson-Nuclear Interactions INR RAS participates in production of start-time detector [T0] for the ALICE experiment.

Precision studies of CP asymmetries and rare decays in the B -
meson systems - project LHCb

the CERN neutrino beam in the Gran Sasso Laboratory - experiment
OPERA

The study of muon pairs by relativistic lead nuclei collision - experiment NA-50 - fixed target experiment for Pb-Pb collisions at 158 GeV/nucleon to investigate di-muon pairs and production of vectors mesons. INR RAS group developed and produced BeO absorber to reduce hadron background and sufficiently improved J/psi mass resolution. The Laboratory of Meson-Nuclear Interactions INR RAS participated in collection and analysis of the experimental data and investigated transverse momentum distributions of J/psi production.
