“Antibaryonic Dark Matter at LHC and HyperK”

Conventional Dark Matter (DM) models do not address the order-of-magnitude coincidence of visible (baryonic) matter and invisible (dark) matter contributions to the total energy density of the present Universe, m_B n_B = rho_B ~ rho_DM=M_DM n_DM. The models called asymmetric, (anti)baryonic DM are specifically designed to explain this coincidence by producing DM and generating Baryon Asymmetry of the Universe (BAU) via one and the same mechanism. If the latter involves scattering, which naturally implies similar number densities, n_DM ~ n_B, then DM particle mass is in GeV range, M_DM ~ m_B and corresponding New Physics scale is high. Concentrating on a particular example of these models we show that, quite remarkably, the Large Hadron Collider has the best opportunity to probe this idea.
