Non-invertible symmetry from the minimal Fibonacci fusion rule forbids tree-level VEVs for multi-Higgs fields H4 and H5, generating them radiatively at one-loop with naturally small values of 10^{-3}-10^{-2} GeV that satisfy the rho parameter.

Dark pions stabilized by U(1) flavor symmetry in an SU(3)/SO(3) dark sector obtain the correct thermal relic density through up-scatterings to heavier mesons and dark eta decays, producing LHC signals from long-lived particle showers.
Above the muon threshold, LFV ALP production in K, D_s, W, Z, J/ψ and τ decays gives new prompt and displaced search channels with projected reach up to f_a ≈ 10^8 GeV.
Zee models are classified under non-invertible Z_M symmetries; viable candidates are identified from data consistency, and a Z_7 benchmark yields numerical predictions for neutrino parameters and CLFV rates.
One-loop corrections in the complex Higgs triplet model shift the 125 GeV Higgs decay rates to WW* and ZZ* upward by a few percent relative to the SM, while allowing up to -20% deviation in gamma gamma and 100% in the self-coupling.
Tera-Z factories can produce millions of heavy neutral leptons and billions of axion-like particles under optimistic assumptions, turning them into exotics factories for discovery and detailed study.
Observing vector boson fusion production of a heavy scalar followed by decay to Z h1 at muon colliders can establish CP violation in the scalar sector because it requires both h2VV and h2h1Z couplings to be nonzero.
Muon colliders at 3 TeV and 10 TeV can probe branching ratios for h to SS decays in 4b and 2b2μ channels down to 10^{-3}–10^{-5}, improving on HL-LHC projections using machine learning.
Computes production cross sections and sensitivity limits for heavy ALPs in light-by-light scattering at FCC-hh across pp, pPb, and PbPb modes.

A theoretical account of tiny multi-Higgs vacuum expectation values from non-invertible symmetry
Non-invertible symmetry from the minimal Fibonacci fusion rule forbids tree-level VEVs for multi-Higgs fields H4 and H5, generating them radiatively at one-loop with naturally small values of 10^{-3}-10^{-2} GeV that satisfy the rho parameter.
