Luminogenesis from Inflationary Dark Matter

TL;DR

This paper proposes a cosmological model where dark matter dominates early universe evolution, unifies gauge groups, and explains the origin of luminous matter and matter asymmetry, challenging traditional grand unification theories.

Contribution

It introduces a novel dark matter-centric cosmological model with a specific gauge group unification, explaining luminous matter generation and matter asymmetry.

Findings

Dark matter dominates for T > 10^9 GeV

Luminous matter is generated at T ~ 10^9 GeV

Challenges grand unification theories involving only luminous matter

Abstract

A cosmological model is introduced in which dark matter plays a dominant role throughout the history of the universe, and is the only matter present for temperatures $T \gtrsim T_{15} \sim 10^9$ GeV. The gauge group is $SU(3) \times SU(6)_{DM} \times U(1)_Y$ and unifies in such a way that luminous matter is generated at $T \sim T_{15}$ with the correct amount and eventual asymmetry. Construction of more highly sensitive direct detectors of dark matter (e.g. XENON1T) is encouraged. We offer a new explanation of why grand unification theories involving only luminous matter may be fatally flawed.
