Vadim Alexeevich Kuzmin, born on April 16, 1937 and died September 17, 2015, he was a Russian theoretical physicist.
Vadim completed his undergraduate studies in 1961 at Moscow State University and his PhD in 1971 at Lebedev Institute.
He has been a member of the Institute for Nuclear Research in Moscow since its founding in 1970.
There, he became a professor and chair of the department of particle astrophysics and cosmology.
In 1987, he obtained the Russian doctoral title.
In the 1980s, Vadim was a pioneer in the theory of elektroweak baryogenesis.
In 1985, Vadim influential work with Valery Rubakov and Mikhail E. Shaposhnikov estimated the rate of anomalous electroweak process that violated baryon-number conservation in the cosmic plasma of the early universe.
In neutrino physics, he proposed an experiment using gallium/germanium detectors to detect solar neutrinos.
In 1970, Vadim proposed neutron/antineutron oscillations as a possibility for observing violation of baryon number.
In 1970, he independently discovered the Sakharov conditions.
In 1966, he and Georgiy Zatsepin predicted (what is now called) the GZK limit for cosmic rays.
In 2000, Vadim became a corresponding member of the Russian Academy of Sciences. In 2006, he received the Pomeranchuk Prize with Howard Georgi. In 2003, he received the Moisey Markov Prize.
Kuzmin died at age 78 on September 17, 2015.
