Exploring the landscape for soft theorems of nonlinear sigma models
Abstract We generalize soft theorems of the nonlinear sigma model beyond the O $$ \mathcal{O} $$ (p 2) amplitudes and the coset of SU(N) × SU(N)/SU(N). We first discuss the universal flavor ordering of the amplitudes for the Nambu-Goldstone bosons, so that we can reinterpret the known O $$ \mathcal{...
