Isospin breaking corrections to the HVP at the physical point

Understand

A determination of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon from lattice QCD aiming at a precision of $1\%$ requires to include isospin breaking corrections in the computation.

• We present a lattice calculation of the QED and strong isospin breaking corrections to the hadronic vacuum polarization with Domain Wall fermions.
• The results are obtained using quark masses which are tuned such that pion and kaon masses agree with their physical values including isospin breaking corrections.
