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 …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

Following updates in the compilation of e+ e-→ hadrons data, this work presents
reevaluations of the hadronic vacuum polarization contributions to the anomalous magnetic …

We address the contribution of the 3 π channel to hadronic vacuum polarization (HVP) using
a dispersive representation of the e+ e−→ 3 π amplitude. This channel gives the second …

We present a detailed analysis of e+ e−→ π+ π− data up to s= 1 GeV in the framework of
dispersion relations. Starting from a family of ππ P-wave phase shifts, as derived from a …

This work presents a complete reevaluation of the hadronic vacuum polarization
contributions to the anomalous magnetic moment of the muon, a μ had, VP, and the …

A bstract In this third paper of a series dedicated to a dispersive treatment of the hadronic
light-by-light (HLbL) tensor, we derive a partial-wave formulation for two-pion intermediate …

A bstract Searches for dark photons provide serendipitous discovery potential for other types
of vector particles. We develop a framework for recasting dark photon searches to obtain …

At low energies hadronic vacuum polarization (HVP) is strongly dominated by two-pion
intermediate states, which are responsible for about 70% of the HVP contribution to the …

A bstract We present B q→ ρ, B q→ ω, B q→ K∗, B s→ K∗ and B s→ ϕ form factors from
light-cone sum rules (LCSR) at\(\mathcal {O}\left ({\alpha} _s\right)\) for twist-2 and 3 …
