Magnetic field modifications to the pion-quark vertex in the Linear Sigma Model with quarks
Alejandro Ayala, Flávia Fialho, Adrián Lara +2
We compute the modification to the quark-neutral pion vertex, induced by a constant and uniform magnetic field, using the Linear Sigma Model with quarks as a low energy effective t…

Mass and coupling magnetic field dependence in a scalar theory with charged bosons from an environmentally friendly renormalization group analysis
Alejandro Ayala, Flávia Fialho, Ana Mizher
We compute the running of the mass of a neutral boson and of its self-coupling in a simple model describing the self-interaction of three scalars, one of them neutral and the other…
