Higgs boson structure from the shape of the cross section in exchange processes

TL;DR

This paper explores how Higgs boson exchange processes can reveal potential substructures or dark matter interactions through modifications in the energy dependence of their cross sections, using the muon-antimuon to fermion-antifermion process as an example.

Contribution

It introduces a method to detect Higgs boson substructures or dark matter interactions by analyzing changes in the cross section's energy dependence.

Findings

Modified s-dependence signals Higgs substructure or dark matter interactions

Analysis of mu+ mu- to f fbar process demonstrates the approach

Potential to identify new physics in Higgs exchange processes

Abstract

We show how the Higgs boson exchange processes may indicate the occurence of special Higgs boson structures (substructures or peculiar interactions with dark matter) from a possible modification of the s-dependence of their cross section. We illustrate the simplest example with the $\mu^+\mu^-\to f\bar f$ process.
