Electromagnetic contributions to vector meson masses and mixings
Summary, in English
We use the 1/Nc method to estimate electromagnetic contributions to vector meson masses and mixings. We identify several new sources of ρ - ω mixing coming from short-distance effects. We comment on the extraction of quark masses from the vector meson masses. We also present a simple group theoretical discussion of the electromagnetic mass differences.
