Abstract
En 中文
We introduce simple group-theoretic techniques for classifying conformally-invariant tensor structures. With them, we classify tensor structures of general n-point functions of non-conserved operators, and n >= 4-point functions of general conserved currents, with or without permutation symmetries, and in any spacetime dimension d. Our techniques are useful for bootstrap applications. The rules we derive simultaneously count tensor structures for flat-space scattering amplitudes in d + 1 dimensions.
