Isospin Violation in Pion-Nucleon Scattering at Threshold
T. E. O. Ericson
We discuss the electromagnetic corrections to the pion-nucleon scattering lengths generated by minimal e. m. coupling from a knowledge of the low energy expansion of the pion-nucle…

Isospin breaking in pion-nucleon scattering at threshold by radiative processes
T. E. O. Ericson, A. N. Ivanov
We investigate the dispersive contribution by radiative processes such as (pi- proton to neutron gamma) and (pi- proton to Delta gamma) to the pion-nucleon scattering lengths of ch…
