Description
I will examine the feasibility of composite dark sectors, in which the full Standard Model (including the Higgs boson) is extended with a new strongly-interacting composite sector with global symmetry group G spontaneously broken to some subgroup H. I will demonstrate that, under well-motivated conditions, the lightest neutral pNGBs are natural dark matter candidates for they are protected by a parity symmetry not even broken in the electroweak phase. In particular, I will show that the neutral pNGBs are good dark matter candidates in a large region of the parameter space, being compatible with current bounds from dark matter searches as well as electroweak and collider constraints on new resonances.
