Fundamental nuclear physics

Photoproduction of heavy mesons, experiment GRALL
(Laboratoire de Physique Subatomique et de Cosmologie, Grenoble;
Institut de Physique Nucle'aire, Orsay, France).
Study of static, dynamical (nucleon resonances), spin nucleon structure using the monochromatic polarized back scattered gamma beam.
Contribution of INR RAS: creation, maintenance work of the electromagnetic shower calorimeter, data handling and data analysis.

High Acceptance Di-Electron Spectrometer - HADES
( Gesellschaft fur Schwerionenforschung - GSI, Darmstadt, Germany).
It's main research activity is focused to the investigation of in medium properties of light vector mesons in dense nuclear matter. Despite that the present knowledge of the properties of light vectors mesons in vacuum is well investigated, a set of theoretical models predict that properties of light vector mesons surrounded by strong interacting matter might be noticebly altered.
INR's Laboratory of Meson-Nuclear Interactions collaborated in manufacturing of the TOFINO detector. In addition, expluatation of the TOFINO and partially of the Forward Wall detectors is driven by INR RAS.

Study of nucleon and nuclear structure with real photons. A2-collaboration - experiments with real photons on MAMI (MAinzer MIcrotron), (Institut fur Kernphysik of the Johannes Gutenberg-Universitut, Mainz, Germany).
Study of dynamical (nucleon resonances), spin structure of nucleons and few nucleon systems using the Bremsstrahlung tagged (polarized and unpolarized) photons. Pioneering experiments with polarized both target and beam.
INR RAS participates in creation and maintenance of targets and detector systems, experiment simulations, data handling and data analysis.

Electron-Ion scattering in a Storage Ring (eA Collider), project ELISe
(Gesellschaft fur Schwerionenforschung - GSI, Darmstadt, Germany).
Study of exotic nuclei far from the stability region by electron scattering in the colliding electron - ion beams.
Contribution of INR RAS: simulation and development of the detector system for magnetic spectrometer and luminosity monitor, experiment is planned to start in 2015.

Presently, preparation to the CBM experiment which will be focused to studies of compressed baryon matter in GSI, Darmstadt, is one of our current investigation projects related to future plans. The interest to the CBM experiment is related to the plan for upgrade of the GSI accelerator complex up to 20-40 GeV/nucleon. This will allow investigations in some specific region of compression and baryon density which has potential for the discovery of a new phase of nuclear matter.
