Due to the fermion sign problem, standard lattice Monte-Carlo method for QCD\nfail at small temperatures and high baryon densities. G2-QCD, QCD with the\ngauge group SU(3) replaced by the exceptional Lie group G2, can be\nsimulated using lattice techniques at these densities, and can therefore\nprovide an illustration of the possible phase structure. Here we present a\nsystematic investigation of the ground-state hadronic spectrum using lattice\nsimulations for different quark masses in several hadronic sectors. We then\nshow that the different hadronic scales of Goldstone bosons, intermediate\nbosons, and baryons is reflected in the phase structure at finite density.\n
