 +   <​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
