Description

Reducing the uncertainty of the Standard Model $g-2$ determination is a crucial task. A key issue is the discrepancy between lattice-QCD and data-driven hadronic vacuum polarization (HVP) results. A path to resolve this discrepancy is the precise data-driven determination of the isospin-limit light-quark connected (lqc) and strange plus light-quark disconnected (s+lqd) components of the HVP contribution. We will present data-driven evaluations of the isospin-limit lqc and s+lqd components of the RBC/UKQCD window results for the HVP contribution to the muon g-2. The results will be compared with the most recent lattice determinations. We will discuss the role of the recent CMD-3 measurements of $e^+e^-\to \pi^+\pi^-$ and present new results based on hadronic $\tau$ decays.
