Naturalness and theoretical constraints on the Higgs boson mass
A. R. Vieira, Brigitte Hiller, M. C. Nemes +1
Arbitrary regularization dependent parameters in Quantum Field Theory are usually fixed on symmetry or phenomenology grounds. We verify that the quadratically divergent behavior re…
Supergravity corrections to the factor by Implicit Regularization
J. E. Ottoni, A. P. Baeta Scarpelli, Marcos Sampaio +1
We apply Implicit regularization in the calculation of the one-loop graviton and gravitino corrections to the anomalous magnetic moment of the lepton in unbroken supergravity, whic…
Symmetries and Ambiguities in the linear sigma model with light quarks
E. W. Dias, Brigitte Hiller, A. L. Mota +3
We investigate the role of undetermined finite contributions generated by radiative corrections in a linear sigma model with quarks. Although some of such terms…
The Role of hidden ambiguities in the Linear Sigma Model with fermions
Brigitte Hiller, A. L. Mota, M. C. Nemes +2
The Linear Sigma Model (LSM) with quark degrees of freedom is used to show that radiative corrections generate undetermined finite contributions. Their origin…
The Chiral Fermion Meson Model at Finite Temperature
H. C. G. Caldas, A. L. Mota, M. C. Nemes
We study the chiral fermion meson model which is the well known linear sigma model of Gell-Mann-and-Levy at finite temperature.A modified self-consistent resummation (MSCR) which r…
Meson Properties in a renormalizable version of the NJL model
Andre L. Mota, M. Carolina Nemes, Brigitte Hiller +1
In the present paper we implement a non-trivial and renormalizable extension of the NJL model. We discuss the advantages and shortcomings of this extended model compared to a usual…
Low-energy dynamics of the reaction
B. Bajc, A. H. Blin, B. Hiller +3
We calculate the one-quark-loop amplitude for the low energy collision in the context of the Nambu and Jona-Lasinio model with scalar and pseudoscalar four quark coupling…
Momentum Dependent Vertices , and : The NJL Scalar Hidden by Chiral Symmetry
B. Bajc, A. H. Blin, B. Hiller +2
We calculate the momentum dependence of three particle vertices , and in the context of a Nambu Jona Lasinio type model. We show how they influence the processes $…
