Barger graduated from
Pennsylvania State University in 1960 with a B.S. in engineering science and in 1963 with a Ph.D. in theoretical physics. His doctoral advisor was Emil Kazes. In the physics department of the
University of Wisconsin–Madison (UW–Madison), Barger became in 1963 a research associate, in 1965 an assistant professor, in 1968 full professor, and in 1983 the J. H. Van Vleck Professor of Physics. At UW–Madison he held a Hillsdale Professorship from 1987 to 1991 and since 1991 has held a Vilas Professorship. Barger has done research on
collider physics phenomenology (especially related to the
Large Hadron Collider),
Higgs bosons,
supersymmetry, and the
Grand Unified Theory, as well as "
neutrino oscillations, particle
dark matter,
early universe cosmology, heavy
quarks and the
Regge pole model." He has held visiting appointments at
CERN (1972), at
Durham University (1983), at the
University of Hawaii (1970, 1979, and 1982), at the
Kavli Institute for Theoretical Physics in Santa Barbara, at
Rutherford Appleton Laboratory (1972), at
SLAC (1975), at the
University of Tokyo, and at the
University of Washington. He was a
Guggenheim Fellow for the academic year 1971–1972. In 1998 he was a Frontier Fellow am
Fermilab. In 2021 he received the
Sakurai Prize for "pioneering work in collider physics contributing to the discovery and characterization of the
W boson,
top quark, and Higgs boson, and for the development of incisive strategies to test theoretical ideas with experiments." ==Selected publications==
