$π^{0}$ - $γ$ mixing in the presence of a strong magnetic field

D. Gomez Dumm, S. Noguera, N. N. Scoccola

We analyze the mixing between the $π^{0}$ meson and the photon in the presence of a strong uniform magnetic field, in the context of a two-flavor Nambu-Jona-Lasinio model. It is show…

Masses of magnetized pseudoscalar and vector mesons in an extended NJL model: the role of axial vector mesons

Máximo Coppola, Daniel Gomez Dumm, Santiago Noguera +1

We study the mass spectrum of light pseudoscalar and vector mesons in the presence of an external uniform magnetic field $B$ , considering the effects of the mixing with the ax…

Magnetic field driven enhancement of the weak decay width of charged pions

M. Coppola, D. Gomez Dumm, S. Noguera +1

We study the effect of a uniform magnetic field $B$ on the decays $π^{-} \to l^{-} ν ˉ_{l}$ , where $l^{-} = e^{-}, μ^{-}$ , carrying out a general analysis that includes four $π^{-}$ deca…
