| + | <hidden TTP95-31 On the Corrections to Dashen's Theorem > The electromagnetic corrections to the masses of the pseudoscalar | ||
| + | mesons $\pi$ and $K$ are considered. We calculate in chiral | ||
| + | perturbation theory the contributions which arise from resonances | ||
| + | within a photon loop at order $O(e^2 m_q)$. | ||
| + | Within this approach we find rather moderate deviations to Dashen's | ||
