Magnetic field driven enhancement of the weak decay width of charged pions
Abstract We study the effect of a uniform magnetic field B → $$ \overrightarrow{B} $$ on the decays π − → l − ν ¯ l $$ {\pi}^{-}\to {l}^{-}{\overline{\nu}}_l $$ , where l − = e −, μ −, carrying out a general analysis that includes four π − decay constants. Taking the values of these constants from a...
