Zemach and Friar radii of the proton and neutron from lattice QCD
Dalibor Djukanovic, Georg von Hippel, Harvey B. Meyer +3
We present the first lattice-QCD result for the Zemach and Friar radii of the proton and neutron. Our calculation includes both quark-connected and -disconnected diagrams and asses…

Precision calculation of the electromagnetic radii of the proton and neutron from lattice QCD
Dalibor Djukanovic, Georg von Hippel, Harvey B. Meyer +3
We present lattice-QCD results for the electromagnetic form factors of the proton and neutron including both quark-connected and -disconnected contributions. The parametrization of…

Electromagnetic form factors of the nucleon from lattice QCD
Dalibor Djukanovic, Georg von Hippel, Harvey B. Meyer +3
There is a long-standing discrepancy between different measurements of the electric and magnetic radii of the proton. Lattice QCD calculations are a well-suited tool for theoretica…
