Type II Seesaw Higgs Triplet as the inflaton for Chaotic Inflation and Leptogenesis

TL;DR

This paper proposes a model where the Higgs triplet in the type II seesaw mechanism acts as the inflaton in chaotic inflation, enabling leptogenesis without supersymmetry.

Contribution

It introduces a novel inflationary scenario using the Higgs triplet as the inflaton within a non-SUSY framework, linking neutrino mass generation and leptogenesis.

Findings

Higgs triplet can drive chaotic inflation

Leptogenesis occurs after inflation in this model

Model operates without supersymmetry

Abstract

In this paper, we consider a chaotic inflation model where the role of inflaton is played by the Higgs triplet in type II seesaw mechanism for generating the small masses of left-handed neutrinos. Leptogenesis could happen after inflation. This model is constructed without introducing supersymmetry (SUSY).
