Distinguishing the Higgs scalars of NMSSM and Z' models for large Higgs trilinear couplings

TL;DR

This paper compares the Higgs spectra of NMSSM and Z' models with large trilinear couplings, proposing collider-based methods to distinguish between them at both tree and loop levels.

Contribution

It provides a comparative analysis of Higgs spectra in NMSSM and Z' models and suggests collider processes to differentiate these models.

Findings

Higgs spectra differ at tree and loop levels between models.

Bjorken processes at $e^+e^-$ colliders can distinguish the models.

Distinctive collider signatures are identified for each model.

Abstract

Two well-known extended supersymmetric models, Z' models and NMSSM, are comparatively analyzed in the limit of large trilinear Higgs couplings. The two models are found to have distinguishable Higgs spectra at both tree- and loop- levels. Higgs production through Bjorken processes at an $e^+e^-$ collider is shown to discriminate between the two models.
