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…
