Abstract

The KNTW (Keshavarzi-Nomura-Teubner-Wright) data-driven determinations of the hadronic vacuum polarization (HVP) are crucial inputs to previous and future Standard Model (SM) predictions of the muon’s anomalous magnetic moment, aμ. With the muon g−2’s new physics case uncertain due to disagreeing HVP evaluations, new SM predictions and experimental measurements of aμ expected soon, and a complete revamp of the KNTW analysis framework underway, this Letter motivates and describes a blinding scheme for data-driven HVP determinations that has been implemented for future KNTW analyses.
