Functional RG flow of the effective Hamiltonian action
G. P. Vacca, L. Zambelli
After a brief review of the definition and properties of the quantum effective Hamiltonian action we describe its renormalization flow by a functional RG equation. This equation ca…

Ward Identities for Amplitudes with Reggeized Gluons
J. Bartels, L. N. Lipatov, G. P. Vacca
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 ac…
