A new evaluation of the hadronic vacuum polarisation contributions to the muon anomalous magnetic moment and to $\mathbf{\boldsymbol\alpha(m_Z^2)}$ / Davier, M. (Orsay, LAL) ; Hoecker, A. (CERN) ; Malaescu, B. (Paris U., VI-VII) ; Zhang, Z. (Orsay, LAL)
We reevaluate the hadronic vacuum polarisation contributions to the muon magnetic anomaly and to the running of the electromagnetic coupling constant at the $Z$-boson mass. We include newest $e^+e^- \to$ hadrons cross-section data together with a phenomenological fit of the threshold region in the evaluation of the dispersion integrals. [...]

Reevaluation of the hadronic vacuum polarisation contributions to the Standard Model predictions of the muon g-2 and alpha(mZ) using newest hadronic cross-section data / Davier, Michel (Orsay, LAL) ; Hoecker, Andreas (CERN) ; Malaescu, Bogdan (Paris U., VI-VII) ; Zhang, Zhiqing (Orsay, LAL)
We reevaluate the hadronic vacuum polarisation contributions to the muon magnetic anomaly and to the running of the electromagnetic coupling constant at the Z-boson mass. We include newest e+e- to hadrons cross-section data (among others) from the BABAR and VEPP-2000 experiments. [...]

Reevaluation of the Hadronic Contributions to the Muon g-2 and to alpha(MZ) / Davier, Michel (Orsay, LAL) ; Hoecker, Andreas (CERN) ; Malaescu, Bogdan (Orsay, LAL) ; Zhang, Zhiqing (Orsay, LAL)
We reevaluate the hadronic contributions to the muon magnetic anomaly, and to the running of the electromagnetic coupling constant at the Z-boson mass. We include new pi+pi- cross-section data from KLOE, all available multi-hadron data from BABAR, a reestimation of missing low-energy contributions using results on cross sections and process dynamics from BABAR, a reevaluation of all experimental contributions using the software package HVPTools together with a reanalysis of inter-experiment and inter-channel correlations, and a reevaluation of the continuum contributions from perturbative QCD at four loops.

Tensions in $e^+e^-\rightarrow \pi ^+\pi ^-(\gamma )$ measurements: the new landscape of data-driven hadronic vacuum polarization predictions for the muon $g - 2$ / Davier, Michel (IJCLab, Orsay) ; Hoecker, Andreas (CERN) ; Lutz, Anne-Marie (IJCLab, Orsay) ; Malaescu, Bogdan (LPNHE, Paris) ; Zhang, Zhiqing (IJCLab, Orsay)
The situation of the experimental data used in the dispersive evaluation of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon is assessed in view of two recent measurements: $e^+e^- \to \pi^+\pi^-$ cross sections in the $\rho$ resonance region by CMD-3 and a study of higher-order radiative effects in the initial-state-radiation processes $e^+e^- \to \mu^+\mu^-\gamma$ and $e^+e^- \to \pi^+\pi^-\gamma$ by BABAR. The impact of the latter study on the KLOE and BESIII cross-section measurements is evaluated and found to be indicative of larger systematic effects than uncertainties assigned. [...]

The Hadronic Contribution to the Muon Anomalous Magnetic Moment and to the Running Electromagnetic Fine Structure Constant at MZ - Overview and Latest Results / Hoecker, Andreas (CERN)
Quantum loops induce an anomaly, a_mu, in the magnetic moment of the muon that can be accurately measured. Its Standard Model prediction is limited in precision by contributions from hadronic vacuum polarisation of the photon. [...]

The SM prediction of g-2 of the muon / Hagiwara, K ; Martin, A D ; Teubner, Thomas ; Nomura, Daisuke
We calculate (g-2)/2 of the muon, by improving the determination of the hadronic vacuum polarisation contribution, a_mu^{had,LO}, and its uncertainties. The different e+e- data sets for each exclusive (and the inclusive) channel are combined in order to obtain the optimum estimate of the cross sections and their uncertainties. [...]

The prospect of charm quark magnetic moment determination / Fomin, A.S. (Orsay, LAL ; Kharkov, KIPT ; CERN) ; Barsuk, S. (Orsay, LAL) ; Korchin, A.Yu. (Kharkov, KIPT ; Kharkov Natl. U.) ; Kovalchuk, V.A. (Kharkov, KIPT ; Kharkov Natl. U.) ; Kou, E. (Orsay, LAL) ; Liul, M. (Orsay, LAL ; Kharkov Natl. U.) ; Natochii, A. (Orsay, LAL ; Taras Shevchenko U.) ; Niel, E. (Orsay, LAL) ; Robbe, P. (Orsay, LAL) ; Stocchi, A. (Orsay, LAL)
In this paper, we discuss the theoretical framework and the experimental measurements of the magnetic moment of the charm baryons. The $\Lambda_c^+$ magnetic moment is particularly interesting since it is equal to the magnetic moment of the charm quark. [...]
