Description
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 s-channel and get constraints for the dark matter particle mass by comparison to astrophysical constraints.
