Description
The anomalous magnetic moment of the muon is a promising quantity for discovering new physics, and exhibits a tension between the experimental measurement and the current Standard Model prediction. However, this prediction has been relying on determining the hadronic vacuum polarisation (HVP) contribution using complementary experimental data (R-ratio). Recently, lattice QCD calculations of the HVP have reached precision competitive to the R-ratio determinations. In this talk I will review the status of theory predictions of the HVP, and present recent results of the RBC/UKQCD collaboration for the long-distance contribution to the HVP.
