The scientific seminar was organized at the Laboratory of High Energy Physics of the Physical-Technical Institute of the Academy of Sciences of Uzbekistan. The tasks of the seminar are the conduct of scientific discussions, the analysis of the current and urgent problems of high-energy physics, the physics of the atomic nucleus and elementary particles. The seminar provides recommendations for research of various problems in the field of high-energy physics, atomic nucleus and elementary particle physics. In the seminar, thesis for the Doctor of Physical and Mathematical Sciences (DSc), PhD (PhD) in physics and mathematics is approbated and gives recommendations for consideration in the Scientific Council for presentation to the defense. The seminar deals in detail with issues related to multiple generation of particles and the processes of fragmentation of relativistic nuclei. Approbation of scientific articles of authors - employees of the Laboratory of High Energy Physics is regularly carried out and the seminar gives a recommendation on elimination of shortcomings of work and after taking into account comments and seminar participants a recommendation is made for its open publication. The seminar examines and analyzes the current state of scientific works of applicants for DSc and PhD degrees, the state of registration of dissertations.
