The muon anomalous magnetic moment, a_mu, is one of the most precisely known quantities in physics. The measurement of a_mu in 2021 by the FNAL E989 experiment (at Fermilab) has confirmed the tension between the experimental result and the predictions based on the Standard Model of particle physics. The SM prediction relied, for a long time, on a data-based dispersion relation for the had…
With the recent experimental measurement of g - 2of the muon at Fermilab, this observable shows now a tension at level of 4.2 standard deviations with respect to the standard model predictions. In the present research project, we will build a realistic model for the cross-section for e+e- to hadrons, from which the hadronic vacuum polarization contribution to the muon g -2 can be extracte…
The determination of the Quantum Chromodynamics (QCD) coupling, alpha_s, from the theoretical description of inclusive tau in (hadrons) + nu_tau decays, dominated by perturbative QCD, is one of the most precise as extractions from experimental data. In these decays, the hadronic vector and axial vector spectral functions are experimentally accessible. Recently, we have shown that the vect…
