Title: Where are the next Higgs bosons?

Abstract

Simple symmetry arguments applied to the third generation lead to a prediction: there exist new sequential Higgs doublets with masses of order $$\lesssim 5 $$ TeV, with approximately universal Higgs-Yukawa coupling constants, $$g\sim 1$$. 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 $$g\sim 1$$ is predicted, and may be accessible to the LHC at $13$ TeV, and definitively at the energy upgraded LHC of $26$ TeV. The extension to leptons determines a new $$H_\tau$$ and a potential $$H_{\nu_\tau}$$ doublet. The accessibility of the latter depends upon whether the mass of the $$\tau$$-neutrino is Dirac or Majorana.

FIG. 1 FIG. 1: The fine-tuning associated with different values of the Mb and Mτ parameters. The remaining three parameters μ, μτ, and MH are fixed by the physical choices of fermion masses and Higgs VEV. The red dashed line corresponds to $M^{2}_{H}$ = 0 and the origin to $M^{2}_{H}$ = −|$M^{2}_{0}$|.
