Keith Olive

Keith Alison Olive (* 1956 ) is an American theoretical physicist who studies elementary particle physics and cosmology.

Olive graduated from the University of Chicago with a bachelor's degree in mathematics in 1978 and a master's degree in physics that same year. In 1981 he received his doctorate in physics from David Schramm in Chicago with a dissertation on cosmology and astroparticle physics. In 1982/83 he was at CERN (including with John Ellis ), where he began to deal with supersymmetry .

Olive is a professor at the University of Minnesota and from 1999 to 2005 and director of the Fine Theoretical Physics Institute from 2011. In 1998 he became a Distinguished McKnight University Professor at his university.

He was particularly concerned with the nucleosynthesis of light elements and baryogenesis in the early days of the universe.

Another focus of his research is supersymmetry. In 2002 he published with other Snowmass (after the conference venue Snowmass in Colorado) reference points in the parameter space for the experimental differentiation of supersymmetric theories, for example at the LHC . In 2003, together with John Ellis and others, he determined the density of supersymmetric matter inferred from WMAP as a candidate for dark matter and found restrictions on areas in the parameter space of supersymmetric theories (WMAP strips). For example, they predicted almost equal masses for the lightest and second lightest supersymmetric particles (usually the supersymmetric partners of neutrino and tau lepton).

In 1985, together with Joseph Silk and Mark Srednicki, he proposed that dark matter could be detected using high-energy neutrinos from the sun. The neutrinos come from the annihilation of dark matter that would have concentrated in the sun over time.

From 1987 to 1994 he received the Presidential Young Investigator Award and in 2003 he became a Fellow of the American Physical Society , which awarded him its Hans A. Bethe Prize for 2018 . In 1988 he received the George W. Taylor Award from the University of Minnesota.

He has been a member of the Particle Data Group since 1987 .
