André Petermann

Andreas Emil Petermann (27 September 1922, Lausanne, Switzerland – 21 August 2011, Lausanne), known as André Petermann, was a Swiss theoretical physicist known for introducing the renormalization group, suggesting a quark-like model, and work related to the anomalous magnetic dipole moment of the muon.

[8] Jointly with his advisor, Ernst Stueckelberg, in 1953, they introduced, and named the "renormalization group", which describes the running of physical couplings with energy.

[9][3] He also, apparently independently, considered the idea of quarks, albeit in a highly abstract, speculative form.

[10] Petermann submitted a four-page paper entitled "Propriétés de l'étrangeté et une formule de masse pour les mésons vectoriels"[11] to the journal Nuclear Physics, which received the paper on 30 December 1963, but did not publish the article before March 1965.

[13] [14] Petermann is also remembered for his pioneering calculation of the next-to-leading order correction to the anomalous magnetic dipole moment of the muon.
