Scientific Programme:
Studies of the generalized parton distributions in various exclusive processes. Studies of the exclusive production of photons, pions and vector mesons in DIS and DVCS. Measurements of nucleon structure in the Drell-Yan processes. Study of inclusive and semi-inclusive processes in Deep Inelastic Scattering (DIS) of muons and hadrons on polarized targets.
- Measurements of the nucleon structure functions, polarized parton distributions.
- Measurements of nucleons structure in the Drell-Yan processes.
- Studies of the inclusive production of photons, pions and
-mesons in DIS and DVCS.
- Software creation and development for simulation and data analysis. System support of CERN software in COMPASS-II.
- Detector preparation for the COMPASS-II spectrometer.
- Measurement of asymmetries in processes of the exclusive birth of photons (DVCS),
-mesons and vector mesons.
- Participation in the data taking.
- Maintenance of the hadron calorimeter HCAL1 and muon system MW1.
- Preparation for a data taking the new electromagnetic calorimeter ECALO. Support of ECALO during data taking.
- Software development and simulation of the various reactions, studied in COMPASS-II. Analyzing
of the COMPASS-II data at JINR and publications preparation.
- Theoretical studies for COMPASS-I and COMPASS-II.
