Gerschtein 2011

Semjon Solomonowitsch Gerschtein ( Russian Семён Соломонович Герштейн ; English transcription Semen (or: Semyon) Solomonovich Gershtein; born July 13, 1929 in Harbin ) is a Russian theoretical physicist.

Gerschtein studied at Moscow's Lomonosov University and, after graduating in 1951, was sent to the Kaluga region as a rural teacher for three years, as was customary at the time . In 1954 he returned to Moscow, but could only find a job as a reviewer at the Institute for Scientific Information. Soon afterwards he became a student of Lev Landau and a member of his research group in Moscow. At Landau he passed his special exams ( theoretical minimum ). In 1958 he received his doctorate and went to the Physics-Technical Institute in Leningrad , where he was a colleague of Vladimir Gribov in the theory department under Ilya Schmuschkewitsch . In 1960 he was at the United Institute for Nuclear Research in Dubna (Moscow) . In 1963 he completed his habilitation (Russian doctorate). Later he was a scientist at the particle accelerator facility "Serpukhov" (Research Institute for High Energy Physics, IHEP) in Protvino and professor at the Moscow Institute for Physics and Technology .

Gerschtein dealt with many areas of theoretical physics. Together with Jakow Seldowitsch , he developed the VA theory of the weak interaction in 1956 independently of Richard Feynman , Murray Gell-Mann , Robert Marshak and George Sudarshan . Also with Seldowitsch, he gave upper limits for neutrino masses for cosmological reasons (the observed rate of expansion of the universe) and wrote early work on muon-catalyzed fusion , with which he later continued. Gerschtein and Seldowitsch also dealt with pair generation in supercritical fields from the vacuum, for example in heavy ion collisions, from 1969 onwards.

Gerschtein is a member of the Russian Academy of Sciences (corresponding member since 1984, full member since 2003). In 1996 he received the Bruno Pontecorvo Prize , in 2011 the Pomerantschuk Prize , and in 2013 the Landau Prize .

Later calculations improved this (for this estimation method) to below 100 eV for the sum of the neutrino masses.
