Description
I will review a recently discovered connection (Nima Arkani-Hamed, et al) between tree-level amplitudes of massless Pions and that of a massless scalar in the adjoint of $U(N)$. The scattering of massless Pions can be described by a $U(N)$ Non-Linear Sigma Model Lagrangian. Using the Feynamn rules derived from this Lagrangian, I will outline the salient features of Pion amplitudes such as their vanishing under soft limits. I will then give a brief overview of amplitudes in the adjoint scalar theory. I will conclude by explaining a kinematic deformation that allows one to obtain Pion amplitudes from that of the adjoint scalar.
