2. Non-perturbative regime: Strongly coupled DM and quarkonia systems, phase transitions of QCD and new physics particles in the early Universe

We consider strongly interacting dark matter candidates as composite states of Nf=2 fermions charged under a dark Sp(4) gauge group in the fundamental representation. We calculate correlation functions of two pseudo-Nambu-Goldstone-bosons on the lattice and present first results of the scattering phase shift in the isospin-2 channel. We calculate the self-interaction cross-section in the...
