The $π^{0} \to γ^{} γ^{}$ transition form factor and the pion pole contribution to $a_{μ}$ on CLS ensembles

Jonna Koponen, Antoine Gerardin, Harvey B. Meyer +2

We present the status of the Mainz group's lattice QCD calculation of the pion transition form factor $F_{π^{0} γ^{*} γ^{*}}$ , which describes the interaction of an on-shel…

The isoscalar octet axial form factor of the nucleon from lattice QCD

Alessandro Barone, Dalibor Djukanovic, Georg von Hippel +4

The isoscalar axial-vector form factor of the nucleon plays a key role in understanding the electroweak interaction of nucleons. For the interpretation of the spin structure of the…

The isoscalar non-singlet axial form factor of the nucleon from lattice QCD

Alessandro Barone, Dalibor Djukanovic, Georg von Hippel +4

We present our progress on the computation of the axial form factor of the nucleon with flavour structure $u + d - 2 s$ from lattice QCD. We employ a set of $N_{f} = 2 + 1$ CLS ensembles with…
