Issues addressed and main goals of research:
Comprehensive investigations of superhigh-energy (7-14 TeV) proton scattering at the Large Hadron Collider with the ATLAS facility will yield utterly new and unique experimental data. Their analysis will allow solution to the most profound physical problems fundamentally important for world outlook.
JINR researchers will take part in solution of some of these problems within the project. Among the most important of them are the clarification of the origin of the elementary particle mass (Higgs mechanism) and search for and investigation of supersymmetry, which will allow an insight into the nature of galactic dark matter and the character of the evolution of our Universe. Other important problems are determination of the applicability boundaries of the modern standard model of elementary particles and observation of evidence for new physical phenomena, such as additional space dimensions or previously unknown particles and interactions. In addition, JINR researchers will get new results allowing more specific knowledge as to the properties of the already known elementary particles such as the W and Z bosons, the top quark, and others.
Implementation of this project aimed at solving highly important scientific problems will result in getting unique applied data.
The "by-products" worth noting are development, debugging, and experience in operation of systems for remote monitoring of highly complicated devices and development and practical use of the distributed computation system (grid) in a long-term, full-scale experiment. 

Expected major results in the current year:

• Participation in the LHC and ATLAS detector maintenance and upgrades. 
  
  
• Data development and analysis of the ATLAS data. The new physical results to be obtained in investigations of some key processes of the Standard Model,exotic physics, search for SUSY and heavy quarks physics. 
  
  
• Development of the ATLAS physics programme: simulation of physical processes, participation in the ATLAS working group, etc. 
  
  
• Work on the modernization project of the ATLAS detector, including the toroidal magnets, hadron calorimeters and muon spectrometer, as well as development of a new detectors. 
  
  
• Detector maintenance and operation.
