The lowest-energy of these should have a mass $m_{1/2}$ comparable to the mass $m_h$ of the recently discovered Higgs boson, with $m_{1/2} = m_h$ in the simplest model. These particles should therefore be detectable in collider experiments, perhaps in Run 2 or 3 of the LHC. They cannot decay through any obvious mechanisms in standard physics, making them a new dark matter candidate. In the simplest model, annihilations would p","authors_text":"Johannes Kroll, Joshua Stenzel, Minjie Lei, Roland E.
