The $I$ = 1/2 and 3/2 $K-\pi$ scattering length with domain wall fermions at physical pion mass with all-to-all propagators / Asmussen, Nils (Southampton U.) ; Erben, Felix (Piemonte Orientale U., Alessandria ; INFN, Turin) ; Flynn, Jonathan (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN) ; Mukherjee, Rajnandini (Southampton U.) ; Sachrajda, Christopher T. (Southampton U.)
We present our calculations for the $I$ = 1/2 and 3/2 $K-\pi$ s-wave scattering length with physical quark masses, extracted from the interaction energy of Euclidean two-point functions. We use the domain wall fermion action with physical quark masses at a single lattice spacing. [...]

A variance reduction technique for hadronic correlators with partially twisted boundary conditions / Barone, Alessandro (Southampton U.) ; Asmussen, Nils (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN)
Partially twisted boundary conditions are widely used for improving the momentum resolution in lattice computations of hadronic correlation functions. The method is however expensive since every additional twist requires computing additional propagators. [...]

(CERN ; Mainz U., Inst. 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. [...]

Developments in the position-space approach to the HLbL contribution to the muon $g-2$ on the lattice / Asmussen, Nils (Southampton U.) ; Chao, En-Hung (U. Mainz, PRISMA) ; Gérardin, Antoine (DESY, Zeuthen) ; Green, Jeremy R. (CERN) ; Hudspith, Renwick J. (U. Mainz, PRISMA) ; Meyer, Harvey B. (U. Mainz, PRISMA ; Helmholtz Inst., Mainz) ; Nyffeler, Andreas (U. Mainz, PRISMA)
The measurement of the anomalous magnetic moment of the muon and its prediction allow for a high-precision test of the Standard Model (SM). In this proceedings article we present ongoing work combining lattice QCD and continuum QED in order to determine an important SM contribution to the magnetic moment, the hadronic light-by-light contribution.
