Dieter Haidt

Dieter Haidt (born 1940) is a German physicist, known for his contribution to the 1973 discovery of weak neutral currents.[1][2] The discovery was made in the Gargamelle experiment, which used a heavy liquid bubble chamber detector in operation at CERN from 1970 to 1979.[3]

Education and career

In 1958 Haidt graduated from the Kepler-Gymnasium in Tübingen. He then studied physics at the University of Tübingen, where he graduated with a Diplom in experimental physics in 1965. He then moved to RWTH Aachen University, where he was a member of the X2 collaboration.[4][5] He was also a visiting scholar at University College London in 1966. In 1969 he received his doctorate at RWTH Aachen University summa cum laude[4][6] and in 1970 he received the Borchers Medal. From 1970 he was a member of the Gargamelle collaboration at CERN (from RWTH Aachen University) and from 1971 to 1978 he was employed at CERN.[4] In 1973, the Gargamelle collaboration discovered weak neutral currents.[7] The collaboration searched for weak neutral currents in neutrino reactions without muon generation. The discovery's rapid recognition depended, to a considerable extent, on calculations by Haidt, who showed that the existence of weak neutral currents was a new type of effect (and not, e.g., interactions between neutrons).[2][4] Other prominent physicists involved in the Gargamelle experiment include Antonino Pullia (1935–2020), Helmut Faissner (1928–2007), and André Lagarrigue (1924–1975).[8]

Haidt was a spokesperson for the neutrino-propane experiment at the Gargamelle bubble chamber. He was involved in neutrino experiments at the BEBC detector. From 1979 to 2004 he was a senior scientist at DESY. From 1979 to 1986 he was a member of the JADE collaboration at DESY and from 1994 of the H1 collaboration. He was a member of the Physics Research Committee (PRC) at DESY and organized the DESY seminars. In 2007 he received emeritus status.[4]

For the academic year 1987–1988 he was a visiting scientist at Japanese particle physics laboratory known as KEK.[4]

In 2011 he shared the Enrico Fermi Prize with Antonino Pullia.[1][2] In 2009, the Gargamelle collaboration received the European Physical Society's High-Energy and Particle Physics Prize.[1]

From 1986 to 1997 he was an editor for the Zeitschrift für Physik C and from 1997 to 2006 he was the editor-in-chief of its successor, the European Physical Journal C.[4]
