INR RAS - international collaborations
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.
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 -
Hadrons are particles that take part in the strong interactions – the force that binds quarks together and keeps atomic nuclei from falling apart. The SPS Heavy Ion and Neutrino Experiment NA61/SHINE studies the properties of the production of hadrons in collisions of beam particles (pions, and protons, beryllium, argon and xenon) with a variety of fixed nuclear targets.
The main aim of the NA62 experiment is to study rare kaon decays. Understanding these decays will help physicists to check some of the predictions the Standard Model makes about short-distance interactions. Specifically, NA62 will measure the rate at which the charged kaon decays into a charged pion and a neutrino-antineutrino pair.
The CERN Axion Solar Telescope (CAST) aims to shed light on a 30 year old riddle of particle physics by detecting axions originating from the 15 million degree plasma in the Sun's core.
AEGIS - Antimatter Experiment Gravity Interferometry Spectroscopy is a physics experiment that takes place at the european laboratory CERN, using the antiprotons delivered by the AD accelerator.
The primary scientific goal of the AEGIS experiment is the direct measurement of the Earth’s gravitational acceleration g on antihydrogen. In the first phase of the experiment, a gravity measurement with 1% precision will be carried out by sending an antihydrogen beam through a classical Moire deflectometer coupled to a position sensitive detector. This will represent the first direct measurement of a gravitational effect on an antimatter system.
The ICARUS program concerns the usage of Liquid Argon (LAr) detector for studies of neutrinos from CNGS beam. The ICARUS detector filled with 600 tons of liquid argon, T600, has started data taking in 2010. The detector is placed at the undeground laboratory in Gran Sasso. The advantage of the LAr detector is its excellent spatial and calorimetric resolution which makes possible a perfect visualization of tracks of the charged particles.
В настоящее время в ЦЕРН в рамках программы модернизации Большого адронного коллайдера начато сооружение линейного ускорителя отрицательных ионов водорода Linac-4.
The experiment NA64 at the SPS CERN aims at the searches for new physics beyond the Standard model, The main focus is on the searches for new
light, < 1 GeV particles from dark sectors which interact very weakly with
the our matter. An example of such particle is the, so-called, dark
photon, A', mixing with the ordinary photons. Interestingly, the existence
of the A' could explain the discrepancy between the measured and predicted
values of the muon anomalous magnetic moment. The search for the A'
decaying invisible into the lighter dark sector particles is the main
goal of NA64 in 2016. The experiment was prepared with the active
participation of the INR team.
The LHC employs a novel computing system, a distributed computing and data storage infrastructure called the Worldwide LHC Computing Grid (WLCG). In ‘The Grid’, tens of thousands of standard PCs collaborate worldwide to have much more processing capacity than could be achieved by a single supercomputer, giving access to data to thousands of scientists all over the world.
