abstract

The grand unified group $E_6$~is a predictive scheme for physics beyond the standard model (SM). It offers the possibility of extra $Z$ bosons, new vector-like fermions, sterile neutrinos, and neutral scalars in addition to the SM Higgs boson. Some previous discussions of these features are updated and extended. Their relevance to present searches at the CERN Large Hadron Collider and in patterns of neutrino masses is noted. Addition of a small set of scalar bosons at the TeV scale permits gauge unification near a scale of $10^{16}$ GeV, and leads to bounds on masses of particles beyond those in the standard model.

  1. Investigating vector-like leptons decaying into an electron and missing transverse energy in e$^{+}$ e$^{-}$ collisions with $\sqrt{s} = 500$ GeV at the ILC

    hep-ex 2024-11 conditional novelty 6.0 of 10

    Simulated ILC data at 500 GeV with 1000 fb^-1 would exclude vector-like leptons up to about 100-180 GeV for small mass splittings, and across the whole studied range for a 100 GeV splitting, at a Yukawa coupling of 0.1.

  2. Searching for vector-like leptons decaying into an electron and missing transverse energy in e$^{+}$e$^{-}$ collisions with $\sqrt{s} = 240$ GeV at the FCC-ee

    hep-ex 2026-04 unverdicted novelty 4.0 of 10

    Monte Carlo projections for FCC-ee at 240 GeV set 95% CL exclusion limits on vector-like lepton mass and Yukawa coupling in a lepton-portal scalar dark-matter scenario if no signal appears.

  3. Prospects for probing neutral vector-like leptons via pair production at muon collider

    hep-ph 2026-06 unverdicted novelty 3.0 of 10

    Simulations indicate a 6 TeV muon collider with 4 ab^{-1} can reach >5σ significance for neutral doublet VLLs of 1.3-3 TeV mass using 4j2μ and 2ℓ2μ + missing energy channels under polarized beams.
