WW Scattering in the Era of Post Higgs Discovery

TL;DR

This paper investigates the potential for additional Higgs bosons or new physics to influence WW scattering processes at the LHC, using the two-Higgs-doublet model as a case study.

Contribution

It analyzes the sensitivity of WW scattering signals at 13 TeV LHC to heavy extra Higgs bosons within the two-Higgs-doublet model framework.

Findings

WW scattering becomes strong with very heavy extra Higgs bosons

Sensitivity estimates for detecting such effects at the 13 TeV LHC

Implications for electroweak symmetry breaking mechanisms

Abstract

More evidences have now been collected at the Large Hadron Collider suggesting the new 125 - 126 GeV boson is likely the long sought Higgs boson in the standard model. One pressing question continued being asked by theorists is whether this Higgs boson is a lone player responsible for the full electroweak symmetry breaking. Current data still allow room for additional Higgs bosons or some other UV physics that may play a partial role in electroweak symmetry breaking as well. We use the WW scattering to investigate such a possibility, using the two-Higgs-doublet model as a prototype. The WW scattering becomes strong when the extra Higgs bosons are very heavy. We study the sensitivity of the partially strong WW scattering signals at the 13 TeV Large Hadron Collider.
