Jack Steinberger (1920-2020) – in memoriam on the third anniversary of his death.

• prof. dr hab. Jan Krolikowski (University of Warsaw (PL))

Room: Room: B2.38 Abstract: Jack Hans Steinberger (1921- 2020) was an outstanding experimental particle physicist. Among his discoveries/ measurements are proof of the three-body decay of a muon (PhD 1949 ), the discovery of the π0 meson, practical implementation of the bubble chambers as a tool for accelerator physics (BNL 195-1963), experimental discovery of the difference between muon and electron neutrinos (Nobel Prize 1988 with L. Lederman and M. Schwarz), a plethora of precise measurements of the mixing and CPV in the neutral kaon system (Columbia and CERN), precise measurements of neutrino interactions with iron. (CDHS(W) experiment), ALEPH experiment at LEP. I worked with Jack in the CHSW neutrino experiment during the 1979-1989 decade. I learned from him a lot. At the third anniversary of His death, I would like to give a commemorative talk discussing His experimental heritage, focusing on the not so well known earlier results. Serdecznie zapraszamy dr hab.
