We propose a new experiment to measure the running of the electromagnetic coupling
constant in the space-like region by scattering high-energy muons on atomic electrons of a …

We reassess the impact of short-distance constraints for the longitudinal component of the
hadronic light-by-light amplitude on the anomalous magnetic moment of the muon, a μ=(g-2) …

The electromagnetic form factors of charged and neutral kaons are strongly constrained by
their low-energy singularities, in the isovector part from two-pion intermediate states and in …

We study the possibilities of a search for the light and weakly interacting gauge boson in the
gauged model. Introducing the kinetic mixing at the tree level, the allowed parameter …

We argue that high-quality data on the reaction e^+ e^-→ π^+ π^-η e+ e-→ π+ π-η will allow
one to determine the doubly-virtual form factor η → γ^* γ^* η→ γ∗ γ∗ in a model …

The contributions to the anomalous magnetic moment of the lepton L (\(L= e\,\mu\) or\(\tau\))
generated by a specific class of QED diagrams are evaluated analytically up to the eighth …

We review recent developments in the evaluations of the muon anomalous magnetic
moment, putting some emphasis on the leading-order hadronic contribution to it. We also …

The evaluation of hadronic light-by-light scattering contribution to the muon anomalous
magnetic moment (a μ) relies on our understanding of meson-photon transition form factors …
