Christopher T. Hill (born June 9, 1951) is an American 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 Schrödinger 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.
