Academician V.G. KADYSHEVSKY
05.05.1937 – 24.09.2014

On 24 September 2014, the outstanding Russian physicist-theoretician and science organizer, the Scientific Leader of the Joint Institute for Nuclear Research RAS Academician Vladimir Georgievich Kadyshevsky died suddenly.

Vladimir Georgievich Kadyshevsky was a prominent scientist in elementary particle theory and high energy physics. The name of V.G.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 forereached the research in “non-commutative geometry” in the 1990s which have become today the focus of theoreticians’ attention. In the theory of internal symmetry V.G.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 to the most challenging and principle issues in physics, creative approaches in research and rich intuition were his outstanding features.

V.G.Kadyshevsky was born on 5 May 1937 in Moscow. In the years of 1946-1954 he studied at the Suvorov Military School in Sverdlovsk. Having graduated from the School with summa cum laude, Vladimir Georgievich entered the physics department of the Lomonosov Moscow State University. Immediately in the first years of studies he expressed interest to theoretical physics. In 1959 his Diploma Thesis “On Mass Spectrum and Fundamental Length in Field Theory” (scientific leader – D.V.Shirkov, referee – M.A.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.G.Kadyshevsky graduated from the University and continued his studies as a post-graduate at the Chair of N.N.Bogoliubov. In 1962 V.G.Kadyshevsky successfully defended his PhD Thesis and started his work at the Laboratory of Theoretical Physics of JINR.

From 1964, V.G.Kadyshevsky published a cycle of papers dedicated to covariant Hamiltonian formulation of the 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 on interaction of two relativistic particles allowed him to cut the number of variables and establish the 3D integral equation for the relativistic scattering amplitude known now in references as the V.G.Kadyshevsky equation. The approach of V.G.Kadyshevsky, which is theoretically consistent, allows one to transfer research methods, intuition and experience accumulated in the theory of analogous non-relativistic systems, as, for example, 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.

From 1970 V.G.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 disciples of Vladimir Georgievich became famous scientists and work successfully in scientific centres in Russia and abroad. On numerous occasions he guided the work of schools for young scientists, international symposia and conferences.
On the initiative of V.G.Kadyshevsky in 1994 a new university was opened in Dubna that was named the International University of Nature, Society and Man. In 1995 Vladimir Georgievich became its President.

In 1977-1978 V.G.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.N.Bogoliubov, V.G.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.G.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 considerably enhanced its positions. In this period the research was implemented and received great response in the world scientific community: experiments on the first in Russia 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 programs in particle physics at facilities of JINR and other large scientific centres in the world.  In recent years V.G.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 scientific-organizational activities of Vladimir Georgievich was very wide. He was member of the RAS Presidium, and the Expert Advisory Board under the Chairman of the RF Accounts Chamber. For a number of years V.G.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.G.Kadyshevsky received Prizes of NAS of Ukraine – the N.Krylov Prize (1990) and the N.Bogoliubov Prize (2001), the N.Bogoliubov Prize (JINR, 2006). He was the Honorary Doctor of several foreign universities, Honorary or Foreign Member of different Academies.

V.G.Kadyshevsky was honorary citizen of Dubna and the Moscow region, holder of Orders of Friendship, Honour and “For Merit 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).

Vladimir Georgievich 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, extraordinary commitment to work. These features combined in his character with unacquired refinement, amiable and kind attitude to people.

Friends, disciples and colleagues of Vladimir Georgievich Kadyshevsky will always remember him in their hearts.
