We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon $g-2$ Theory Initiative to update the Standard Model prediction..

The anomalous magnetic moment of the muon in the Standard Model

Phys. ; Darmstadt, GSI ; Helmholtz Inst., Mainz) ; Colangelo, G. (U. Bern, AEC) et al.
We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure constant $\alpha$ and is broken down into pure QED, electroweak, and hadronic contributions. [...]

openQ*D code: a versatile tool for QCD+QED simulations
/ Campos, Isabel (Cantabria Inst. of Phys.) ; Fritzsch, Patrick (CERN) ; Hansen, Martin (INFN, Rome) ; Marinkovic, Marina Krstic (TCD, Dublin) ; Patella, Agostino (Humboldt U., Berlin) ; Ramos, Alberto (TCD, Dublin) ; Tantalo, Nazario (Rome U., Tor Vergata ; INFN, Rome)
/RC* Collaboration
We present the open-source package openQ*D-1.0, which has been primarily, but not uniquely, designed to perform lattice simulations of QCD+QED and QCD, with and without C* boundary conditions, and O(a) improved Wilson fermions. The use of C* boundary conditions in the spatial direction allows for a local and gauge-invariant formulation of QCD+QED in finite volume, and provides a theoretically clean setup to calculate isospin-breaking and radiative corrections to hadronic observables from first principles.

openQ*D simulation code for QCD+QED
/ Campos, Isabel (Madrid, IFT ; Cantabria Inst. of Phys.) ; Fritzsch, Patrick (CERN) ; Hansen, Martin (Southern Denmark U., CP3-Origins) ; Marinković, Marina Krstić (CERN ; Trinity Coll., Dublin) ; Patella, Agostino (CERN ; Plymouth U., Math. Stat. Dept.) ; Ramos, Alberto (CERN) ; Tantalo, Nazario (Rome U., Tor Vergata ; INFN, Rome2)
The openQ*D code for the simulation of QCD+QED with C$^\star$ boundary conditions is presented. This code is based on openQCD-1.6, from which it inherits the core features that ensure its efficiency: the locally-deflated SAP-preconditioned GCR solver, the twisted-mass frequency splitting of the fermion action, the multilevel integrator, the 4th order OMF integrator, the SSE/AVX intrinsics, etc. [...]

Computing the muon anomalous magnetic moment using the hybrid method with physical quark masses
/ Spraggs, Matthew (Southampton U.) ; Boyle, Peter A (Edinburgh U.) ; Del Debbio, Luigi (Edinburgh U.) ; Izubuchi, Taku (Brookhaven ; RIKEN BNL) ; Jüttner, Andreas (Southampton U.) ; Lehner, Christoph (Brookhaven) ; Maltman, Kim (York U., Canada ; U. Adelaide, Sch. Math. Sci.) ; Marinkovic, Marina Krstic (CERN) ; Portelli, Antonin (Southampton U. ; Edinburgh U.)
I present our work on the leading strange quark-connected contribution to the muon anomalous magnetic moment using RBC/UKQCD physical point domain wall fermion ensembles. I also present preliminary results of a computation of the light quark-connected contribution using a similar approach..
