Also an acronym for “Not Even Wrong.”The year is 2016, and physicists are restless. Four years ago, the LHC confirmed the Higgs-boson, the last outstanding prediction of the standard model. The chances were good, so they thought, that the LHC would also discover other new particles – naturalness seem to demand it. But their hopes were disappointed. The standard model and general relativity do a great job, but physicists know this can’t be it. Or at least they think they know: The theories are incomplete, not only disagreeable and staring each other in the face without talking, but inadmissibly wrong, giving rise to paradoxa with no known cure. There has to be more to find, somewhere. But where?The hiding places for novel phenomena are getting smaller. But physicists haven’t yet exhausted their options. Here are the most promising areas where they currently search: 1. Weak CouplingParticle collisions at high energies, like those reached at the LHC, can produce all existing particles up to the energy that the colliding particles had. The amount of new particles however depends on the strength by which they couple to the particles that were brought to collision (for the LHC that’s protons, or their constituents ...
