Description

Recent results from the muon $g-2$ experiment at Fermilab suggest a possible discrepancy between the experimental value of and the theoretical prediction for the muon anomalous magnetic moment $a_\mu$. Results from lattice QCD and the recent CMD-3 experiment make the situation more complicated and raise further questions.

An updated theoretical prediction for $a_\mu$ should be prepared for comparison to the upcoming analysis of the Fermilab run 4 to 6 data. I will present work from updating the KNT compilation of hadronic cross section data used for the $a_\mu$ prediction, focusing on the creation of a relational database and the introduction of blinding to the analysis.
