Vadim Alexejewitsch Kuzmin
Vadim Alexeevich Kuzmin ( Russian Вадим Алексеевич Кузьмин , English transcription Vadim Alexeevich Kuzmin ; born April 16, 1937 in Moscow ; † September 17, 2015 ibid) was a Soviet or Russian theoretical physicist.
After completing his studies at Lomonosov University in 1961, he worked at the Lebedev Institute until his doctorate in 1971 and then at the Institute for Nuclear Physics (INR) of the Soviet Academy of Sciences in Moscow since its establishment in 1970. He became a professor there and headed the department Particle Astrophysics and Cosmology. In 1987 he completed his habilitation ( Russian doctorate ).
He pioneered electroweak baryogenesis in the 1980s . In 1985 he showed in an influential work with Valeri Anatoljewitsch Rubakow and Michail Schaposchnikow (Mikhail E. Shaposhnikov) that the violation of the baryon number in the universe can be explained within the Standard Model at energies in the range of the electroweak phase transition, if the phase transition is 1st order ( a phase of strong thermal non-equilibrium in the early universe must still be assumed).
He dealt with neutrino physics (proposal for a gallium / germanium detector experiment for solar neutrinos) and neutron-antineutron oscillations, which he proposed in 1970 as a way of observing the baryon number violation.
In 1970 he found the Sakharov criteria independently .
The GZK cutoff for the upper limit of the energy of cosmic rays from the interaction with the cosmic background radiation is named after him, Kenneth Greisen and Georgiy Zatsepin (1966).
In 2000 he became a corresponding member of the Russian Academy of Sciences . In 2003 he received the Markov Prize and in 2006 the Pomeranschuk Prize with Howard Georgi .
