91. Hadronic vacuum polarization contribution to the muon g−2 from lattice QCD

Plenary Presentation

The experimental uncertainty on the anomalous magnetic moment of the muon has been significantly reduced with the recent results of the Fermilab g-2 experiment, and a further reduction is expected in the near future. The precision of the Standard Model prediction needs to improve correspondingly to increase the sensitivity of tests for physics beyond the Standard Model. The largest uncertainty...

92. Tau hadronic decay input for Muon g-2

Plenary Presentation

Hadronic tau decay experiments provide an alternative determination of the Hadronic Vacuum Polarization for Muon g-2. The difference in the hadronic cross section between tau-decay and electron-positron collision must be corrected. We review our strategies for such isospin-breaking correction using first-principle Lattice QED+QCD predictions.

33. Global analysis of Lepton Flavor Violating Operators

Plenary Presentation

Processes involving charged lepton flavor violation (CLFV) are very powerful tools to search for new physics beyond the Standard Model and their observation could provide important insight onto the origin of neutrino masses. Probes of CLFV exist across a broad spectrum of energy scales, from low-energy experiments looking for CLFV decays of the muon, of the tau lepton and of a variety of...

72. Status and plans of tau fits for HFLAV/PDG

Alberto Lusiani (Scuola Normale Superiore and INFN, sezione di Pisa)

Plenary Presentation

HFLAV performs a global fit of the tau branching franctions measurements and, for several tau decay modes searches, a combination of the measured upper limits. The status and prospects of these fits are presented.
