Remote Inflation as hybrid-like sneutrino/MSSM inflation

TL;DR

This paper proposes a hybrid-like inflation model involving sneutrino and MSSM fields that avoids the need for direct coupling, shift symmetry, or cancellation, and explicitly incorporates dissipation and radiation effects.

Contribution

It introduces a novel hybrid-like inflation scenario with explicit dissipation and radiation, eliminating the need for direct coupling or shift symmetry.

Findings

Dissipation and radiation are explicitly modeled using Yukawa couplings.

The scenario does not require shift symmetry or cancellation to solve the eta-problem.

It offers an alternative to traditional hybrid inflation models.

Abstract

A new scenario of hybrid-like inflation is considered for sneutrino and MSSM fields. Contrary to the usual hybrid inflation model, the direct coupling between a trigger field and the sneutrino/MSSM inflaton field is not necessary for the scenario. The dissipation and the radiation from the sneutrino/MSSM inflaton can be written explicitly by using the Yukawa couplings. Remote inflation does not require the shift symmetry or cancellation in solving the eta-problem.
