Higgs Inflation at the LC

TL;DR

This paper explores Higgs inflation within the NMSSM framework, highlighting how it significantly alters phenomenology and proposing potential collider signatures to distinguish it from standard models.

Contribution

It introduces a Higgs inflation model in the NMSSM and analyzes its unique phenomenological signatures at future Linear Colliders.

Findings

Distinct Higgs and neutralino/chargino sector signatures

Potential collider observables differentiating inflation models

Altered NMSSM phenomenology due to Higgs inflation

Abstract

Most cosmological models of inflation are far away from providing a smoking gun at low energies. A model of Higgs inflation in the Next-to-Minimal Supersymmetric Standard Model, however, changes the NMSSM phenomenology drastically and may be well distinguished from the pure NMSSM or MSSM at a future Linear Collider. We point out certain differences of the inflationary model to the ordinary NMSSM and discuss the Higgs and neutralino/chargino sector in particular to identify the smoking gun of inflation at electroweak energies.
