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 $\vec{B}$ on the decays ${\pi }^{-}\to l^{-}{\bar{\nu }}_l$, where $l^{-}=e^{-},{\mu }^{-}$, carrying out a general analysis that includes four ${\pi }^{-}$ deca…
