Exploring the standard model of particle physics and finding new physics beyond is in many cases limited by the lack of high-precision knowledge of low-energy QCD effects.

The only known systematically improvable method to compute such effects from first principles is lattice QCD.

For crucial topics such as the muon g-2, heavy-quark flavour physics, and the study of structure functions, the systematic uncertainty associated with the continuum limit of lattice QCD poses one of the most difficult challenges.  

We propose to generate the finest-yet dynamical lattice QCD gauge ensemble using chiral symmetric domain wall fermions to overcome this challenge.

This effort is only possible using the scale of resources made available in the EuroHPC JU Extreme Scale Access call.

The new ensemble will have immediate impact on a high-precision calculation of the hadronic vacuum polarization contribution to clarify emerging tensions for the muon g-2.
