While experimentalists have reached the precision level of 127 ppb\, even better than the one foreseen in the experiment design\, the theoretical va lue has dramatically changed compared to that of the 2020 White Paper\, wi th a precision of 530 ppb\, and is now compatible with the experimental me asurement. In this seminar I will illustrate the reasons that led to this change and finally I will focus on the theoretical calculation of the Hadr onic Light-by-Light diagram from the side of the short distance contributi ons based on the operator product expansion.\n\nAngelo Raffaele Fazio\n\nI EAP\, CTU in Prague\, Husova 240/5\, Prague\, Czech Republic\, Czech Repub lic LOCATION:IEAP\, CTU in Prague\, Husova 240/5\, Prague\, Czech Republic\, Cz ech Republic ORGANIZER:andre.sopczak@cern.ch SEQUENCE:4 SUMMARY:The status of the anomalous magnetic moment of the muon and the con tribution of the Hadronic Light-by-Light diagram URL;VALUE=URI:https://events.vtools.ieee.org/m/522190 X-ALT-DESC:Description: <br /><p>With the publication of the 2025 White Pap er and the final analyses of the Run 1-6\, theorists and experimentalists have updated the muon g-2 value predicted by the Standard Model and that m easured at Fermilab.
