Over the last decade JINR-ATLAS team was deeply involved in designing, construction, tests and assembly of major systems of ATLAS:
Liquid Argon End Cap Calorimeter
Common Items (Toroid Warm Structure and others)
Participation in the Physics Program was always considered as the most important target. Till 2003 this work has been performed mainly in “background” regime, essentially based on individual efforts, promoted with limited resources case-by-case (as well as for software developments and general computing infrastructure of ATLAS).

The status of HEP (semi-)analytical calculation tool for LHC was presented by its leader D.Bardin. At the moment this very ambitious and quickly progressing project is not yet ready for practical investigations of the prospects for observation of the physical phenomena at the LHC with ATLAS detector. Nevertheless it promises to be much more useful for development of the JINR-ATLAS physical program right in the near future.

With the help of the PYTHIA and ATLFAST simulations the prospects for correct verification of the statement that the top-quark electric charge indeed equals to +2/3 is performed on the basis of the lepton-jet top decay channels.
Resonances with several masses are considered (500, 1000, 1500… GeV) with PYTHIA 6.203 event generator and processed with ATLFAST integrated in ATHENA framework.
( V.Bednyakov, S.Kovalenko).
The highest importance of the SUSY search at LHC (especially in connection with cosmology and astrophysics via famous problem of the Dark Matter) needs no any extra arguments Unfortunately, till now there is no any Dubna-based “ATLAS simulation” activity in the field. The situation will be improved in the nearest future.
