Chiral behavior of vector meson self-energies

Zusammenfassung

We employ a chiral Lagrangian framework with three dynamical flavors to calculate the masses of the lowest-lying vector mesons to one-loop accuracy, and use the resulting formulas to extrapolate recent lattice data from the QCDSF Collaboration on vector meson masses and mass ratios to the physical point. Our representation for the vector meson self-energies also enables us to discuss loop corrections to the omega phi mixing amplitude.
