Contributions of inert electroweak multiplets to Higgs properties
Hugues Beauchesne, Cheng-Wei Chiang
TL;DR
This paper investigates how inert electroweak multiplets, which do not mix with Standard Model fields, can influence key Higgs properties such as decay channels and self-couplings, considering experimental and theoretical constraints.
Contribution
It provides a detailed analysis of the effects of inert electroweak multiplets on Higgs observables, a novel exploration of their potential impact on Higgs physics.
Findings
Inert multiplets can significantly modify Higgs decay rates to Z and photon.
Constraints limit the extent of possible modifications to Higgs properties.
The study delineates parameter space consistent with current experimental data.
Abstract
New physics could manifest itself in the form of electroweak multiplets that interact at tree level with the Higgs boson but do not mix with Standard Model fields or acquire expectation values. In this paper, we study the potential contributions of such inert multiplets to several crucial Higgs properties, namely, the branching ratio of the Higgs to a boson and a photon (or massless dark photon) and the triple Higgs coupling. Constraints from the Higgs signal strengths, oblique parameters and unitarity are taken into account.
