Dispersive em corrections to $\pi$N scattering lengths
We investigate the dispersive contribution by radiative processes such as pi/sup negative rightward arrowngamma and pi/sup negative rightward arrowDeltagamma to the piN scattering lengths of charged pions in the heavy baryon limit. They give a large isospin violating contribution in the correspondin...
