Mirza Abdul Baqi Bég
Mirza Abdul Baqi Bég (born September 20, 1934 in Etawah , Uttar Pradesh , † January 30, 1990 in New York City ) was a Pakistani physicist.
Mostly he was quoted MAB Bég, he used the first name Baqi.
After the partition of India, the family moved to Pakistan in 1947 and he grew up in Karachi and attended the University of Hyderabad (Sindh University) with a bachelor's degree in physics in 1951. He then studied at the University of Karachi with a master's degree in applied Mathematics 1954. He then went to the USA and received his doctorate in nuclear physics in 1958 under Philip M. Stehl. As a post-doctoral student he was at the University of Birmingham with Rudolf Peierls from 1958 to 1960 and then at the Brookhaven National Laboratory (BNL). From 1962 to 1964 he was at the Institute for Advanced Study . He then became Assistant Professor (in the laboratory of Abraham Pais ), Associate Professor in 1965 and Professor at Rockefeller University in 1968 , where he later had his own laboratory (Bég Laboratory), where theorists such as Louise Dolan , David Callaway and Mark A. Were ruby . He was also a member of the BNL's High Energy Physics Committee from 1975 to 1978 and also carried out research at SLAC and CERN . He died of a heart attack.
He was a fellow of the American Physical Society . Bég was on the Board of Trustees of the Aspen Center for Physics and editor of the Comments in nuclear and particle physics . His lectures with Sirlin and Guido Altarelli in Mexico City (Polytechnic) in 1969 led to many aspiring Mexican theoretical physicists, who later assumed leadership roles in their country, came to Rockefeller University to do their doctorates.
Bég is known for various contributions to elementary particle physics, for example in the 1960s on quark models with a symmetry group SU (6), a model by Feza Gürsey and Luigi Radicati in which the inner symmetry group SU (3) was extended by the spin. In 1964, together with Benjamin Lee and Abraham Pais, he predicted a ratio of minus two thirds for the ratio of the magnetic moments of neutron and proton from this model, which was considered to confirm the quark model. After establishing the Standard Model, he dealt intensively with gauge field theories and wrote influential reviews with Alberto Sirlin on gauge field theories in weak interaction. He was one of the first to deal with dynamic symmetry breaking and the so-called triviality of the Higgs sector with possible applications on bounds for the Higgs boson mass. He dealt with CP violation , Technicolor models, radiation corrections for beta decay, right-left symmetry in elementary particle physics, scale and conformal invariance, current algebras
In 1961 he established Bég's theorem in the scattering theory of protons on nuclei.
