A Light Dilatonic Higgs and a Dilatonic Inflaton in the Georgi-Glashow SU(5) Model

TL;DR

This paper introduces two dilatonic fields in the Georgi-Glashow SU(5) model, linking one to the Higgs and the other to inflation, with their interaction allowing mass tuning via the Higgs portal.

Contribution

It proposes a novel framework with two dilatonic fields capturing conformal symmetries, connecting Higgs physics and inflation within the SU(5) model.

Findings

Dilatonic Higgs mass can be tuned through coupling constants.

Two conformal symmetries are captured by the dilatonic fields.

A new connection between Higgs physics and inflation is established.

Abstract

In this paper, two dilatonic fields that capture two conformal symmetries in the Georgi-Glashow SU(5) model are introduced. Then, one of the fields is associated with the Higgs, and the other one with inflation. By using the Higgs portal, the mass of the dilatonic Higgs can be tuned by the coupling constant between the two dilatonic fields.
