The multicomponent dark matter structure and its possible observed manifestations

TL;DR

This paper explores a hypercolor extension of the Standard Model with multiple dark matter components, analyzing their interactions, decays, and potential observable effects like dark matter luminescence.

Contribution

It introduces a multicomponent dark matter model within a hypercolor framework and studies its unique decay and transition phenomena with potential observational signatures.

Findings

Charged hyperpions decay into leptons and neutral components.

Heavy dark matter candidates can transition into lighter ones, emitting low-energy photons.

Dark matter luminescence could be observable through photon radiation from charged states.

Abstract

In the framework of hypercolor extension of the Standard Model having vectorlike hyperquarks and two stable dark matter candidates originated from different hyper-currents, we consider some effects which result from reactions with participation of the dark matter components. Namely, there are decays of charged hyperpions into leptons and neutral component, annihilation and transitions of heavy dark matter candidates into the light ones. In the last case, low energy photon radiation from intermediate charged states is possible. This type of the dark matter luminescence is analyzed in more detail.
