- Abstract
- Abstract: (EDP Sciences) The persistent discrepancy of about 3.5 standard deviations between the experimental measurement and the Standard Model prediction for the muon anomalous magnetic moment, aμaμ, is one of the most promising hints for the possible existence of new physics. Here we report on our lattice QCD calculation of the hadronic vacuum polarisation contribution aμhvpaμhvp, based on gauge ensembles with Nf=2+1Nf=2+1 flavours of O(aa) improved Wilson quarks. We address the conceptual and numerical challenges that one encounters along the way to a sub-percent determination of the hadronic vacuum polarisation contribution. The current status of lattice calculations of aμhvpaμhvp is presented by performing a detailed comparison with the results from other groups.
