Tensor and vector formulations of resonance effective theory
arXiv:hep-ph/0701041
Abstract
The main idea of the first order formalism is demonstrated on a toy example of spin-0 particle. The full formalism for spin-1 is applied to the vector formfactor of the pion and its high-energy behaviour is studied.
