Simple symmetry arguments applied to the third generation lead to a prediction: there exist new sequential Higgs doublets with masses of order $\ensuremath{\lesssim}5.5\text{ }\text{ }\mathrm{TeV}$, with approximately universal Higgs-Yukawa coupling constants, $g\ensuremath{\sim}1$. This is calibrated by the known Higgs boson mass, the top quark Higgs-Yukawa coupling, and the $b$-quark mass. A new massive weak-isodoublet, ${H}_{b}$, coupled to the $b$-quark with $g\ensuremath{\sim}1$ is… Expand

LHC probes of the 10 TeV scale
The usual range of new particle masses, up to a few TeV, searched for at the LHC may be substantially extended if ultraheavy diquark particles exist. A diquark scalar, $S_{uu}$, that interactsExpand

We construct an effective field theory (EFT) model that describes matter field interactions with Schwarzschild mini-black-holes (SBH's), treated as a scalar field, $B_0(x)$. Fermion interactions withExpand

We consider composite two-Higgs doublet models based on gauge-Yukawa theories with strongly interacting fermions generating the top-bottom mass hierarchy. The model features a single "universal"Expand

The Higgs mechanism may be a quantum phenomenon, i.e., a Coleman-Weinberg potential generated by the explicit breaking of scale symmetry in Feynman loops. We review the relationship of scaleExpand

This work forms the dynamical symmetry breaking of the standard model by a top-quark condensate by abstracting the compositeness condition for the Higgs boson to boundary conditions on the renormalization-group equations for the full standard model at high energy. Expand

It is considered the possibility that multiple four-Fermi interactions are important in symmetry breaking, leading to an effective two-Higgs-doublet model at low energies, and Higgs-induced flavor-changing neutral currents are naturally suppressed in this model. Expand
