Andrzej Buras
Andrzej Jerzy Buras (: ; born 26 October 1946 in Warsaw, Poland) is a Danish theoretical physicist, professor emeritus at the Technical University Munich (TUM). Scientific career. He received his master's degree in theoretical physics at the Warsaw University in 1971, and emigrated to Denmark in the same year. One year later, he received his PhD at the Niels Bohr Institute in Copenhagen. He then worked as a post-doctoral fellow at the Niels Bohr Institute until 1975. After a fellowship in the CERN theory group from 1975–1977 he was first a visitor and then a staff member in  the Fermilab theory group from 1977 till 1982. He then became staff member of the Max Planck Institute for Physics in Munich (1982–1988). In 1988 finally he was appointed full professor in the Physics Department of the TUM. After his retirement in 2012 he moved to the TUM Institute for Advanced Study where he is leading the focus group 'Fundamental Physics'. Buras is known for his early work on strong-interaction effects (QCD) in deep-inelastic electron-proton and neutrino-proton scattering (1977–1980), which led to the commonly used MS-bar scheme for QCD calculations. But his most important contributions  (1983-now) are in the field of weak decays of mesons; these include high order calculations of QCD effects in most important decays, the phenomenology of CP violation and of quark flavour physics in the Standard Model and in several New Physics models.
