KADYSHVESKIY VLADIMIR GEORGIEVICH

 

05.05.1937 – 24.09.2014

Vladimir Kadyshevsky was a prominent scientist in elementary particle theory and high energy physics. The name of V.Kadyshevsky is connected with the relativistic formulation of the quantum field theory in the quantized space-time that satisfies the unitarity requirements and the generalized causality condition. His works in this field were internationally acknowledged and anticipated the research on non-commutative geometry in the 1990s, which has become today the focus of theoreticians’ attention. In the theory of internal symmetry V.Kadyshevsky postulated a number of correlations for effective cross sections, mass and magnetic moments of hadrons that were proved experimentally. Even before the Standard Model of electroweak interactions was constructed, he studied lepton–hadron symmetries that are revealed in weak processes. His unfailing interest in the most challenging and principal issues in physics, creative approaches in research and rich intuition were his outstanding features.

V.Kadyshevsky was born on 5 May 1937 in Moscow. From 1946 to 1954 he studied at the Suvorov Military School in Sverdlovsk. Having graduated from the School with summa cum laude, Vladimir entered the Physics Department of the Lomonosov Moscow State University. Immediately in the first years of studies he expressed interest in theoretical physics. In 1959 his Diploma Thesis “On Mass Spectrum and Fundamental Length in Field Theory” (scientific leader: D.Shirkov; referee: M.Markov) won the First Prize and was awarded with the Medal of the USSR Ministry of Higher Education at the All-Union competition of students’ theses. In 1960 V.Kadyshevsky graduated from the University and continued his studies as a postgraduate at the Chair of N.Bogoliubov. In 1962 V.Kadyshevsky successfully defended his PhD Thesis and joined the Laboratory of Theoretical Physics of JINR.

From 1964, V.Kadyshevsky published a cycle of papers dedicated to covariant Hamiltonian formulation of quantum field theory. He worked out a unique diagram technique that, unlike the well-known Feynman technique, operates on amplitudes on mass surface. Its application to the problem of interaction of two relativistic particles allowed him to cut the number of variables and establish the 3D integral equation for the relativistic scattering amplitude, now known as the Kadyshevsky equation. Kadyshevsky’s approach, which is theoretically consistent, allows one to transfer research methods, intuition and experience accumulated in the theory of analogous non-relativistic systems, for example, of few-nucleon atomic nuclei, to the sphere of elementary particle physics. It is not by chance that the Kadyshevsky equation is used by physicists from various countries for practical calculations of hadron–hadron interactions and for the description of the hadron quark structure.

Since 1970 V.Kadyshevsky was Professor of the MSU Physics Department where for many years he headed the Elementary Particle Physics Chair. He trained 15 Candidates and 5 Doctors of Science. Many of his disciples became famous scientists and are working successfully in scientific centres in Russia and abroad. He repeatedly guided the work of schools for young scientists, international symposia and conferences. On the initiative of V.Kadyshevsky in 1994 a new university was opened in Dubna that was named the International University of Nature, Society and Man. In 1995 he became its President.

In 1977–1978 V.Kadyshevsky headed a group of Soviet physicists who worked in the E.Fermi National Laboratory (USA), and in 1983–1985 he was the leader of activities in the DELPHI programme at JINR connected to the experiments at the LEP collider (CERN). Theoretical research in this programme was held under his guidance.

In 1987, at the suggestion of Academician N.Bogoliubov, V.Kadyshevsky was elected to the position of Director of the Laboratory of Theoretical Physics of JINR. He served in this position up to 1992 and made an important contribution to the promotion of high scientific traditions of the Dubna theoretical school and development of wide international cooperation.

From 1992 to 2005 V.Kadyshevsky was Head of JINR, one of the largest international scientific centres. In those difficult years he, together with his colleagues, managed not only to maintain the Institute but also to considerably enhance its positions. In that period the research was implemented and received great response in the world scientific community: experiments on the first Russia’s superconducting accelerator of relativistic nuclei, the Nuclotron, were started; the research reactor IBR-2 was upgraded and its neutron beams now have record parameters; an essential breakthrough was achieved in modern nuclear physics — for the first time in the world the synthesis of new superheavy elements was carried out; much progress was achieved in the development of scientific programmes in particle physics at facilities of JINR and other large scientific centres in the world. In recent years V.Kadyshevsky contributed greatly to the development of the main scientific trends and international cooperation of JINR in the position of the Scientific Leader of the Institute.

The range of science-organizational activities of V.Kadyshevsky was very wide. He was member of the RAS Presidium and of the Expert Advisory Board under the Chairman of the RF Accounts Chamber. For a number of years V.Kadyshevsky was President of the Union of Scientific Societies of Russia, Member of the IUPAP board on particles and fields and member of the board under RF President on awarding State Prizes of RF in science and technology.

The scientific achievements of V.Kadyshevsky received Prizes of NAS of Ukraine — the N.Krylov Prize (1990) and the N.Bogoliubov Prize (2001), the N.Bogoliubov Prize (JINR, 2006) and the V.Dzhelepov Prize (JINR, 2014). He was the Honorary Doctor of several foreign universities, Honorary or Foreign Member of different Academies.

V.Kadyshevsky was honorary citizen of Dubna and the Moscow Region, holder of Orders of Friendship, Honour and “For Merits to Motherland” class IV, as well as foreign Orders and Medals, being holder of the Gold Medal of the International Association of Academies of Sciences “For Promotion of Science” (2002) and the Gold Medal “For the Activities for the Benefit of Society” (the Institute of European Integration, 2003).

V.Kadyshevsky was an active advocate of values of fundamental science; he strived to increase the public prestige of the Russian science and the Russian Academy of Sciences. His distinctive features were strong sense of responsibility, devotion to science, ambition, and extraordinary commitment to work. These features combined in his character with unacquired refinement, amiable and kind attitude to people.
