Magnetic field induced anomalous pion couplings
Fabio L. Braghin, Marcelo Loewe, Cristian Villavicencio
Effective pion-constituent quark couplings induced by relatively weak magnetic fields are calculated in the framework based in Weinberg's large Nc Effective Field Theory. These cou…
- scattering lengths: electric corrections in the linear sigma model
M. Loewe, R. Cadiz, R. Zamora
In the frame of the linear sigma model and working in the weak field approximation, we discuss the role played by an external electric field on the behavior of - scattering l…
Electric corrections to - scattering lenghts in the linear sigma model
R. Cadiz, M. Loewe, R. Zamora
In this article we analyze the role of an external electric field, in the weak field approximation, on - scattering lengths. The discussion is presented in the frame of the l…
Magnetic and density effects on the nucleon axial coupling
C. A. Dominguez, M. Loewe, C. Villavicencio +1
Using appropriate QCD finite energy sum rules, we discuss the influence of an external magnetic field and baryonic density on the axial-vector coupling constant . This scena…
QED Fermions in a noisy magnetic field background: The effective action approach
Jorge David Castaño-Yepes, Marcelo Loewe, Enrique Muñoz +1
We consider the effects of a noisy magnetic field background over the fermion propagator in QED, as an approximation to the spatial inhomogeneities and time-fluctuations that would…
The Yukawa potential under weak magnetic field
Fabio L. Braghin, Marcelo Loewe, Cristian Villavicencio
Weak magnetic field induced corrections for the Yukawa potential due to one pion exchange between two constituent quarks (nucleons) are presented. For that, the constant magnetic f…
