Custodial Vector Model

TL;DR

This paper explores the LHC signatures of heavy vector resonances within a custodial symmetry framework, highlighting how this model predicts unique signals in diboson, dilepton, and Higgs channels, and addresses electroweak precision constraints.

Contribution

It introduces a custodial vector model with a specific symmetry structure that influences the spectrum and interactions of heavy vectors, providing new predictions for collider phenomenology.

Findings

Partial protection of the S-parameter by custodial symmetry

Predicted spectrum and interactions of heavy vector resonances

Abstract

We analyze the Large Hadron Collider (LHC) phenomenology of heavy vector resonances with a $SU(2)_L\times SU(2)_R$ spectral global symmetry. This symmetry partially protects the electroweak S-parameter from large contributions of the vector resonances. The resulting custodial vector model spectrum and interactions with the standard model fields lead to distinct signatures at the LHC in the diboson, dilepton and associated Higgs channels.
