Description
Some effects of weak magnetic fields on meson and constituent quark interactions and dynamics are presented at the one loop level within the Weinberg's large Nc effective field theory, and extensions, by considering a dynamical approach. The magnetic field corrections to coupling constants are found to have linear or quadratic dependence on the magnetic field, i.e. $(eB)^n$ for $n=1,2$. Corresponding contributions to the Yukawa potential, and other processes, will be discussed. Leading isotropic weak magnetic field contributions to the low energy constants of Chiral Perturbation theory are also presented.
