MSSM inflaton: SUSY dark matter and LHC

TL;DR

This paper explores how the minimal supersymmetric Standard Model can naturally incorporate inflation, linking inflaton properties to dark matter, baryons, and particle phenomenology without introducing new scalar fields.

Contribution

It demonstrates that inflation can be embedded within the MSSM with the inflaton carrying Standard Model charges, connecting cosmology and particle physics.

Findings

Inflation can be realized within the MSSM framework.

Inflaton properties are directly linked to dark matter and baryon asymmetry.

No additional ad-hoc scalar fields are needed for inflation.

Abstract

In this talk we will discuss how inflation can be embedded within a minimal extension of the Standard Model where the inflaton carries the Standard Model charges. There is no need of an ad-hoc scalar field to be introduced in order to explain the temperature anisotropy of the cosmic microwave background radiation, all the ingredients are present within a minimal supersymmetric Standard Model. For the first time inflaton properties can be directly linked to the particle phenomenology, dark matter, and the baryons of the Standard Model.
