Explanation: SUSY is supersymmetry, a much-sought-for but never yet found phenomenon that physicists hope to simplify the laws of physics with. "Higgs" is the Higgs boson, another predicted but not found particle that many physicists spend their lives looking for. It's supposed to explain where mass comes from.
