Goldstone physics
WebLoop models in two dimensions can be related to O(N) models. The low-temperature dense-loops phase of such a model, or of its reformulation using a supergroup as symmetry, can have a Goldstone broken-symmetry phase for N<2. We argue that this phase is generic for -2< N <2 when crossings of loops are allowed, and distinct from the model of non … WebGriffith’s particle physics goes through this. In the version I have this is from 11.7 on (starting with a section he calls “The Mass Term”). A brief summary is that the initial Langrangian is of a form without a mass term, but then when you find the minimum and expand about that minimum, the Langrangian ends up having a mass term.

We calculate the scattering amplitudes among these four particles and their partial-wave projections in effective theory.
