Understand
Starting from the effective action of high energy QCD we derive Ward identities for Green's functions of reggeized gluons.
- They follow from the gauge invariance of the effective action, and allow to derive new representations of amplitudes containing physical particles as well as reggeized gluons.
- We explicitly demonstrate their validity for the BFKL kernel, and we present a new derivation of the kernel.
