A composite Higgs boson is likely to be accompanied by additional light states generated by the same dynamics. This expectation is substantiated when realising the composite Higgs mechanism by an underlying gauge theory. We review the dynamics of such objects, which may well be the first sign of compositeness at colliders. We also update our previous analysis of the bounds from LHC searches to the latest results, and discuss the projected reach of the High-Luminosity run.

  1. Search for Lorentz-boosted di-$\tau$ resonances produced in association with top quark pairs in $\sqrt{s}=13$ TeV pp collisions with the ATLAS detector

    hep-ex 2026-07 accept novelty 6.5

    No excess is seen; ATLAS sets a 0.19 fb model-independent visible cross-section limit and 2HDM σ×BR limits of 0.4–0.05 pb for ma = 20–85 GeV using boosted di-τ reconstruction.

  2. Composite top partners in exotic colour representations

    hep-ph 2026-05 unverdicted novelty 6.0

    Colour-sextet top partners in composite Higgs models are excluded up to 2-2.5 TeV by current LHC data via top-rich decays, with HL-LHC reach near 3 TeV.

  3. Bounds on massive graviton-like particles from searches for axion-like particles coupling to photons

    hep-ph 2026-05 unverdicted novelty 6.0

    Limits on axion-like particles from photon-coupling searches are recast as constraints on massive graviton-like particles across lab, astrophysical, and cosmological experiments using analogous Primakoff and Gertsensh...

  4. New physics in toponium's shadow?

    hep-ph 2025-12 conditional novelty 6.0

    Consistently including toponium bound-state effects inside the new-physics amplitude, not just the Standard Model one, reshapes the allowed mass–coupling region for a top-philic pseudoscalar near the top-antitop threshold.

  5. SU(2) gauge theory with one and two adjoint fermions towards the continuum limit

    hep-lat 2024-07 unverdicted novelty 5.0

    Extended lattice simulations yield continuum-limit anomalous dimensions γ* = 0.170(6) for Nf=1 and γ* = 0.291(9) for Nf=2 adjoint SU(2), with chiral perturbation theory ruling out spontaneous chiral symmetry breaking.
