Electromagnetic Contributions to Vector Meson Masses and Mixings
نویسنده
چکیده
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.

Vector Meson Masses in Chiral Perturbation Theory
We discuss the vector meson masses within the context of Chiral Perturbation Theory performing an expansion in terms of the momenta, quark masses and 1/Nc. We extend the previous analysis to include isospin breaking effects and also include up to order p. We discuss vector meson chiral perturbation theory in some detail and present a derivation from a relativistic lagrangian. The unknown coeffi...
متن کاملProbing lepton-number/flavour-violation in semileptonic τ decays into two mesons
The evaluation, systematic analysis and numerical study of the semileptonic τ -lepton decays with two mesons in the final state has been made in the frame of the standard model extended by right handed neutrinos. In the analysis, heavy-neutrino nondecoupling effects, finite quark masses, quark and meson mixings, finite widths of vector mesons, chiral symmetry breakings in vector-meson–pseudosca...
متن کاملElectromagnetic Corrections in Staggered Chiral Perturbation Theory
To reduce errors in light-quark mass determinations, it is now necessary to consider electromagnetic contributions to light-meson masses. Calculations using staggered quarks and quenched photons are currently underway. Suitably-extended chiral perturbation theory is necessary to extrapolate the lattice data to the physical limit. Here we give (preliminary) results for light-meson masses using s...
متن کاملElectromagnetic Splittings and Light Quark Masses
A method for computing electromagnetic properties of hadrons in lattice QCD is described. The electromagnetic field is introduced dynamically, using a noncompact formulation. Employing enhanced electric charges, the dependence of the pseudoscalar meson mass on the (anti)quark charges and masses can be accurately calculated. At β = 5.7 with Wilson action, the π − π splitting is found to be 4.9(3...
