Dark Matter in scalar Sp(N) gauge dynamics

Understand

We consider a model with Sp dark gauge group and a scalar field in the fundamental representation, which leads to two co-stable DM candidates at the perturbative level thanks to a global U(1) accidental symmetry.

• After gauge confinement at low energy scale, only one of the two candidates is still stable.
• We compute the DM relic abundance by solving the Boltzmann equations numerically.
• The presence of light dark glueballs gives extra cosmological effects and can affect Higgs physics.
