Calculation of the N*(1238) Electromagnetic Mass Differences by S-Matrix Methods


Henyey, Frank Stephen (1967) Calculation of the N*(1238) Electromagnetic Mass Differences by S-Matrix Methods. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/8E08-7D21.


We calculate the electromagnetic mass differences within the N*(1238) isomultiplet, using the S-matrix theory of perturbations developed by Dashen and Frautschi. An ambiguity in the choice of methods for calculating the effect of one photon exchange, and lack of sufficient data on the rho meson lead to rather large uncertainties in the predicted mass differences. Our results are consistent with experimental determinations of the differences, which also have rather large uncertainties.
