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” …

We review how the muon anomalous magnetic moment (g− 2) and the quest for lepton flavor
violation are intimately correlated. Indeed the decay μ→ e γ is induced by the same …

We present a lattice QCD calculation of the double-virtual neutral pion transition form factor,
with the goal to cover the kinematic range relevant to hadronic light-by-light scattering in the …

We present results for the charged kaon-box contributions to the hadronic light-by-light
(HLBL) correction of the muon's anomalous magnetic moment. To this end we determine the …

Contributions of a spin-0 axionlike particle (ALP) to lepton dipole moments, g-2 and EDMs
are examined. Barr-Zee and light-by-light loop effects from a light pseudoscalar ALP are …

Despite recent developments, there are a number of conceptual issues on the hadronic light-
by-light (HLbL) contribution to the muon (g-2) which remain unresolved. One of the most …

In recent years, the anomalous magnetic moment of the muon has triggered a lot of activity
in the lattice QCD community because a persistent tension of about 3.5~ σ 3.5 σ is observed …

A bstract The recently proposed MUonE experiment at CERN aims at providing a novel
determination of the leading order hadronic contribution to the muon anomalous magnetic …

A confirmation of the long-standing muon g-2 discrepancy requires both experimental and
theoretical progress. On the theory side, the hadronic corrections are under close scrutiny …

Motivated by the experimentally observed deviations from standard model predictions, we
calculate the anomalous magnetic moments a α=(g-2) α for α= e, μ in a neutrino mass model …
