Talal Ahmed Chowdhury, Shaaban Khalil, Ernest Ma
TL;DR
This paper explores how simple left-right models of particle physics naturally include stable dark matter candidates due to added fermion and scalar multiplets, analyzing their relic abundance and detection prospects.
Contribution
It introduces a minimal left-right model framework where dark matter stability arises automatically from the particle content, without extra symmetries.
Findings
Multiple stable dark matter candidates identified within the model
Analysis of relic abundance consistent with observed dark matter density
Predicted signals for direct detection experiments
Abstract
In the simplest left-right extension of the Standard Model of particle interactions with one scalar bidoublet and one triplet for seesaw Majorana neutrino masses, the addition of a variety of fermion and scalar multiplets automatically makes them stable (predestined) dark matter candidates. We discuss the interplay of this dark ensemble in relic abundance and direct searches.
