Conformal Invariance in Momentum Space Seminar

Based on a position space analysis it can be shown that correlation functions i conformal field theories are highly constrained by symmetries. In the talk I will concentrate on the analysis carried out in momentum space. I will present a novel approach, which allows to solve conformal Ward identities directly in momentum space. Furthermore, I will show that all 3-point functions in a CFT involving stress energy tensor, conserved currents and various scalar operators can be easily expressed in terms of (almost) elementary functions.
