In this talk, we will discuss all the three-point Green functions of currents, nontrivial for the odd-intrinsic parity sector. We briefly summarize their basic properties and high energy bahaviour via the OPE framework.
A set of phenomenological studies is introduced. We also refer to a property that the vector field formalism is not compatible with the OPE, and for this reason the antisymmetric field formalism is a more suitable choice.
