  Calculation of the creation cross sections of superpartners at LHC; study of most promising channels for their registration.
  
  Study of properties of gauge theories in extra dimensions in the low-energy region and possibility of their consistent description.
  
  Investigation in to semileptonic pion and kaon decays with additional pair production.
  
  Studies of distribution in the quasiregge kinematics.
  
  
• Investigation of nonperturbative ingredients of QCD factorization - parton distributions (including generalized ones), fragmentation and fracture functions - sensitive to various spin effects will be continued. The results will be applied to the description of experiments at HERA (HERMES), CERN (COMPASS), RHIC and JLAB.
