πe3 Form Factor f- Near the Mass Shell
The generalized Ward-Takahashi identity (gWTI) in the pion sector for broken isotopic symmetry is derived and used for the model-independent calculation of the longitudinal form factor f- of the πe3 vector vertex. The on-shell f- is found to be proportional to the mass difference of the pions and th...
