Probing standard-model Higgs substructures using tops and weak gauge bosons

TL;DR

This paper discusses how gauge-invariance in the Standard Model implies observable states are composite operators involving Higgs contributions, with potential experimental signatures at colliders.

Contribution

It provides estimates of experimental signatures of Higgs substructures involving tops and weak gauge bosons at current and future colliders.

Findings

Gauge-invariance leads to composite operator descriptions of observable states.

Lattice simulations confirm the Higgs contributions beyond perturbation theory.

Potential collider signatures of Higgs substructures are estimated.

Abstract

Manifest gauge-invariance requires that observable states in the standard-model are described by composite operators, which involve additional Higgs contributions beyond perturbation theory. This field-theoretical effect has been confirmed in lattice simulations. It should also be experimentally accessible at high enough precision. Here a few estimates for such signatures at current and future collider experiments will be discussed.
