Pomeron-Odderon Interactions: A Functional RG Flow Analysis
Gian Paolo Vacca
In the quest for an effective field theory which could help to understand some non perturbative feature of the QCD in the Regge limit, we consider a Reggeon Field Theory (RFT) for…
The background scale Ward identity in quantum gravity
Roberto Percacci, Gian Paolo Vacca
We show that with suitable choices of parametrization, gauge fixing and cutoff, the anomalous variation of the effective action under global rescalings of the background metric is…
Pomeron - Odderon interactions in a reggeon field theory
J. Bartels, C. Contreras, G. P. Vacca
In this paper we extend our recent non perturbative functional renormalization group analysis of Reggeon Field Theory to the interactions of Pomeron and Odderon fields. We establis…
Covariant and background independent functional RG flow for the effective average action
Mahmoud Safari, Gian Paolo Vacca
We extend our prescription for the construction of a covariant and background-independent effective action for scalar quantum field theories to the case where momentum modes below…
Covariant and single-field effective action with the background-field formalism
Mahmoud Safari, Gian Paolo Vacca
In the context of scalar quantum field theory we introduce a class of generically nonlinear quantum-background splits for which the splitting Ward identity, encoding the single fie…
Could reggeon field theory be an effective theory for QCD in the Regge limit?
Jochen Bartels, Carlos Contreras, Gian Paolo Vacca
In this paper we investigate the possibility whether, in the extreme limit of high energies and large transverse distances, reggeon field theory might serve as an effective theory…
