Ward Identities in a Two-Dimensional Gravitational Model: Anomalous Amplitude Revisited Using a Completely Regularization-Independent Mathematical Strategy

G. Dallabona, P. G. de Oliveira, O. A. Battistel

We present a detailed investigation of the anomalous gravitational amplitude in a simple two-dimensional model with Weyl fermions. We employ a mathematical strategy that completely…

Analytic results for the massive sunrise integral in the context of an alternative perturbative calculational method

G. Dallabona, O. A. Battistel

An explicit investigation about the equal-mass two-loop sunrise Feynman graph is performed. Such perturbative amplitude is related with many important physical process treated in t…

From scale properties of physical amplitudes to a predictive formulation of the Nambu-Jona-Lasinio model

O. A. Battistel, G. Dallabona

The predictive power of the NJL model is considered in the light of a novel strategy to handle the divergences typical of perturbative calculations. The referred calculational stra…

A predictive formulation of the Nambu--Jona-Lasinio model

O. A. Battistel, G. Dallabona, G. Krein

A novel strategy to handle divergences typical of perturbative calculations is implemented for the Nambu--Jona-Lasinio model and its phenomenological consequences investigated. The…

Extension of the Nambu--Jona-Lasinio model at high densities and temperatures by using an implicit regularization scheme

R. L. S. Farias, G. Dallabona, G. Krein +1

Traditional cutoff regularization schemes of the Nambu--Jona-Lasinio model limit the applicability of the model to energy-momentum scales much below the value of the regularizing c…

Cutoff-independent regularization of four-fermion interactions for color superconductivity

R. L. S. Farias, G. Dallabona, G. Krein +1

We implement a cutoff-independent regularization of four-fermion interactions to calculate the color-superconducting gap parameter in quark matter. The traditional cutoff regulariz…
