Galileogenesis: A new cosmophenomenological zip code for reheating through R-parity violating coupling

TL;DR

This paper proposes a novel leptogenesis scenario within a higher derivative gravity framework, exploring reheating, dark matter, and inflationary constraints, and establishing connections among these cosmological phenomena.

Contribution

It introduces 'Galileogenesis', a new cosmophenomenological approach combining DBI Galileon gravity with R-parity violation, linking reheating, dark matter, and inflation.

Findings

Reheating constraints are thoroughly analyzed.

Thermal gravitino dark matter viability is assessed.

A direct link between dark matter, reheating temperature, and tensor-to-scalar ratio is established.

Abstract

In this paper we introduce an idea of leptogenesis scenario in higher derivative gravity induced DBI Galileon framework {\it aka Galileogenesis} in presence of one-loop R-parity violating couplings in the background of a low energy effective supergravity setup. We have studied extensively the detailed feature of reheating constraints and the cosmophenomenological consequences of thermal gravitino dark matter in light of PLANCK and PDG data. Finally we have also established a direct cosmological connection among dark matter relic abundance, reheating temperature and tensor-to-scalar ratio in the context of DBI Galileon inflation.
