on Meson-Nucleon Physics and the Structure of the Nucleon

In framework of Chiral Perturbation Theory with vector and axial-vector mesons we develop a model for charged and neutral kaon electromagnetic form factors. Regions of time-like and space-like photon momentum are considered. Beyond the tree level the model includes certain loop correc-tions, such as self-energy operators in vector-meson (ρ, ω, φ) propagators and “dressed ” photon-meson vertices. The contribution of ρ ′ = ρ(1450), ω ′ = ω(1420) and φ ′ = φ(1680) resonances is included. Results are com-pared with experimental data on form factors and good agreement is achieved without making a fit. We evaluate KK−channel contribution to the muon anomalous magnetic moment as well.
