Dilaton Forbidden Dark Matter
Thomas Appelquist, James Ingoldby, Maurizio Piai
Dilaton effective field theory (dEFT) describes the long distance behavior of certain confining, near-conformal gauge theories that have been studied via lattice computation. Pseud…
Dilaton Effective Field Theory
Thomas Appelquist, James Ingoldby, Maurizio Piai
We review and extend recent studies of dilaton effective field theory (dEFT) which provide a framework for the description of the Higgs boson as a composite structure. We first des…
Composite two-Higgs doublet model from dilaton effective field theory
Thomas Appelquist, James Ingoldby, Maurizio Piai
We construct a composite two-Higgs-doublet model (2HDM) within the context of dilaton effective field theory. This EFT describes the particle spectrum observed in lattice simulatio…
Goldstone Boson Scattering with a Light Composite Scalar
T. Appelquist, R. C. Brower, K. K. Cushman +14
The appearance of a light composite scalar resonance in nearly conformal gauge-fermion theories motivates further study of the low energy structure of these theories. To this…
A Near-Conformal Composite Higgs Model
Thomas Appelquist, James Ingoldby, Maurizio Piai
We analyze a composite Higgs model based on the confining gauge theory with Dirac fermions in the fundamental representation. This gauge theory has been studied o…
Near-conformal dynamics in a chirally broken system
Thomas Appelquist, Richard C. Brower, Kimmy K. Cushman +11
Composite Higgs models must exhibit very different dynamics from quantum chromodynamics (QCD) regardless whether they describe the Higgs boson as a dilatonlike state or a pseudo-Na…
