Chiral behavior of vector meson self energies

الأصل · EN

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 formulae to extrapolate recent QCDSF lattice data 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 ωϕ mixing amplitude.
