Christopher T. Hill is a theoretical physicist at the Fermi National Accelerator Laboratory. He did undergraduate work in physics at M.I.T. (B.S., M.S., 1972), and graduate work at Caltech (Ph.D., 1977, Murray Gell-Mann). Hill's Ph.D. thesis, "Higgs Scalars and the Nonleptonic Weak Interactions" (1977) contains the first detailed discussion of the two-Higgs-doublet model.[1]

Hill has made contributions to dynamical theories of electroweak symmetry breaking, and is an originator of the top quark infrared fixed point,[2] top quark condensates,[3] topcolor,[4][5] top-seesaw models,[6] and dimensional deconstruction.[7] He is also an originator of cosmological models of dark energy and dark matter based upon ultra-low mass (Nambu-Goldstone) bosons generally associated with neutrino masses.[8]

With David Schramm (astrophysicist), he developed transport equations describing the evolution of the spectrum of ultra-high-energy (UHE) cosmic rays[9] and proposed modern theories of the origin of ultra-high-energy (UHE) nucleons and (UHE) neutrinos from grand unification relics, such as cosmic strings and monopole annihilation.[10][11][12]

In the 1980s he developed functional Schroedinger field theory methods for treating problems in quantum cosmology and carried out detailed calculations of local operator matrix elements at Feynman-loop level in Rindler space.[13][14]

Hill is a Fellow of the American Physical Society and formerly Head of the Theoretical Physics Department at Fermilab (2005 - 2012). He has authored three popular books with Nobel laureate Leon Lederman.
