Violations of Dashen's theorem

Bijnens, Johan LU orcid (1993) In Physics Letters B 306(3-4). p.343-349
Abstract

The electromagnetic contribution to the K+-K0 mass difference is calculated in the 1 Nc approach including the SU(3) breaking contributions due to a non-zero strange quark mass. The short-distance contribution can be unambiguously determined in terms of the known parameters of the next-to-leading order chiral Lagrangian. The long distance part is estimated using the 1 Nc approach by Bardeen et al. Relatively large corrections are found.
