Non-Standard Physics

Many extensions of the Standard Model have been proposed, and likely this represents only a small number of what is possible. Despite different underlying assumptions, many Beyond-the-Standard-Model scenarios predict some common interactions or particles. For instance, new $\mathrm{W}'$ and $\mathrm{Z}'$ gauge bosons can arise in a number of different ways. Therefore it makes sense to cover a few basic classes of particles and interactions, with enough generality that many kinds of detailed scenarios can be accommodated by suitable parameter choices. We have already seen one example of this, in the extended Higgs sector above. In this section a few other kinds of non-standard generic physics scenarios are discussed. Supersymmetry is covered separately in the following section, since it is such a large sector by itself.
