Dark Matter from strongly coupled theories dark baryons and dark pions

概要

Understanding the nature of Dark Matter is one of the most significant open problems in particle physics and cosmology. In this talk, I will explore how Dark Matter candidates can naturally arise as composite bound states in new strongly coupled gauge sectors. I will focus on two specific realizations.

First, I will discuss baryonic Dark Matter in the context of a model for neutrino mass generation. Then, I will examine a model of dark pions, demonstrating how the inclusion of a topological theta term can induce resonant processes, which allow to reproduce the correct Dark Matter relic abundance and address the small-scale anomalies of the Lambda-CDM model.
