Christopher T. Hill

Christopher T. Hill is a theoretical physicist, formerly of the Fermi National Accelerator Laboratory, who did undergraduate work in physics at M.I.T., and graduate work at Caltech. His work mainly focuses on new physics that can be probed in laboratory experiments or cosmology.
Hill is an originator, with William A. Bardeen and Manfred Lindner, of the idea that the Higgs boson is composed
of top and anti-top quarks. This emerges from the concept of the
top quark infrared fixed point, with
which Hill predicted that the top quark would be very heavy, contrary
to most popular ideas at the time. The fixed point prediction
lies within 20% of the observed top quark mass. This implied
that the top quarks may be strongly coupled at very short
distances and could form a composite Brout-Englert-Higgs boson, which led to top quark condensates, topcolor, and dimensional deconstruction, a renormalizable lattice description of extra dimensions of space.
The original minimal top condensation model predicted the Brout-Englert-Higgs boson mass to be
about twice the observed value of 125 GeV. However, this was based upon the Nambu-Jona-Lasinio model,
which lacks an
