Muon g-2 (experiment and theory)
Contributed Oral
I will summarize the status of the dispersive approach to the hadronic light-by-light contribution to the muon $g-2$, and in particular report on recent progress, in particular concerning the role of short-distance constraints.

Muon g-2 (experiment and theory)
Invited Oral
This work presents a complete re-evaluation of the hadronic vacuum polarization contributions to the anomalous magnetic moment of the muon from the combination of e+ e- --> hadrons cross section data. Focus has been placed on the development of a new data combination method, which fully incorporates
all correlated statistical and systematic uncertainties in
a bias free approach. All...

Muon g-2 (experiment and theory)
Invited Oral
The light-by-light contribution to muon anomalous magnetic moment from axial-vector meson exchanges is estimated in the framework of nonlocal quark model. The full kinematic dependence of the transition form-factor is taken into account. The comparison with existed parametrizations based on the experimental data on the transition form factor is performed. The corresponding contribution to the...

Muon g-2 (experiment and theory)
Invited Oral
In this talk, based on arXiv:1811.06743, I will review the NLO electro-weak radiative corrections
to the $\mu^\pm e^-\to\mu^\pm e^-$ process and discuss their relevance for the MUonE
experiment, proposed at CERN.
The aim of MUonE is the high precision measurement of the QED running coupling constant
in the space-like region, from which the full hadronic contribution can be extracted and...

Muon g-2 (experiment and theory)
Contributed Oral
I will present the results of a dispersive analysis of the pion vector form factor, which determines the two-pion contribution to the $(g-2)_\mu$ below 1 GeV. As a by-product, both the $P$-wave $\pi \pi$ phase shift as well as the pion charge radius have been determined with higher precision than before.

Muon g-2 (experiment and theory)
Invited Oral
The study of the anomalous magnetic moment of the muon, Muon g-2, stands as an enduring and stringent test of the Standard Model (SM), where the
current 3.5 standard deviations (or higher) discrepancy between the theoretical prediction and the experimental measurement could be an indication of
new physics beyond the SM. The E989 Muon g?2 experiment at Fermilab aims to measure the muon...
