Dark Nuclei

We consider two-colour QCD with two flavours of quarks as a possible theory of composite dark matter and use lattice field theory methods to investigate nuclear spectroscopy in the spin J=0 and J=1 multi-baryon sectors. We find compelling evidence that J=1 systems with baryon number B=2,3 (and their mixed meson-baryon counterparts) are bound states – the analogues of nuclei in this theory. We discuss aspects of the novel phenomenology of such a dark nuclear sector.
