We review the present status of the Standard Model calculation of the anomalous magnetic
moment of the muon. This is performed in a perturbative expansion in the fine-structure …

We give an overview of the theory for generalized parton distributions. Topics covered are
their general properties and physical interpretation, the possibility to explore the three …

We employ a mathematical framework based on rational approximants in order to calculate
the pseudoscalar-pole piece of the hadronic light-by-light contribution to the anomalous …

Glueballs, hybrids and multiquark states are predicted as bound states in models guided by
quantum chromo dynamics (QCD), by QCD sum rules or QCD on a lattice. Estimates for the …

We propose a new η-η′ mixing scheme where we start from the quark flavor basis and
assume that the decay constants in that basis follow the pattern of particle state mixing. On …

Decays of the neutral and long-lived η and η′ mesons provide a unique, flavor-conserving
laboratory to test low-energy Quantum Chromodynamics and search for new physics …

Investigation at a φ-factory can shed light on several debated issues in particle physics. We
discuss:(i) recent theoretical development and experimental progress in kaon physics …

A key ingredient in the evaluation of hadronic light-by-light (HLBL) scattering in the
anomalous magnetic moment of the muon (g-2) μ concerns short-distance constraints that …

We study the reactions e+ e-→ e+ e-η (′) in the single-tag mode and measure the γ γ*→ η
(′) transition form factors in the momentum-transfer range from 4 to 40 GeV 2. The analysis …
