André Petermann
André Petermann (1922–2011) was a Swiss theoretical physicist.[1]
Jointly with his advisor, Ernst Stueckelberg, in 1953, they introduced, and named the "renormalization group", which describes the running of physical couplings with energy.[2] He also, apparently independently, considered the idea of quarks, albeit in a highly abstract, speculative form.[3] [4] Petermann submitted a four-page paper entitled Propriétés de l'étrangeté et une formule de masse pour les mésons vectorial to the journal Nuclear Physics, which received the paper on 30 December 1963. Petermann discusses what has become known as quarks as named by Murray Gell-Mann, whose Physics Letters publication was submitted during the first days of January 1964, and "aces" as named by George Zweig, who wrote two CERN-TH preprints slightly later in 1964. The publication of Petermann's paper was delayed (probably by referees) and did not appear in print until March 1965.
Petermann is also remembered for his pioneering calculation of the next-to-leading order correction to the anomalous magnetic dipole moment of the muon.[5]
