The basic problems of high energy physics

The basic problems of high energy physics are considered. The present-day consideration on elementary particle interactions is shown. The important problem of strong interactions is to find out the nature of forces between quarks. In the superhigh energy range in collisions of particles and nuclei production of quark-gluon plasma is predicted. The studies of plasma parameters will allow to find out the details of quark and gluon interactions. In the range of weak and electromagnetic interactions the impoptance of detection of W- and Z-bosons, Higgs bosons and search for neutrino oscillations is shown. It is also shown that further development of the superunification theory and investigations of the quark and lepton structure is of great importance
