Abstract
The calculation of the electromagnetic mass shifts of π, K mesons is studied using a model incorporating chiral symmetry and vector dominance. Significant SU(3) breaking to Dashen's theorem is found, allowing a resolution of the long-standing discrepancy between the quark-mass ratio (md-mu)/ms found from η→3π decay and that from the K+-K0 mass difference.
