Proton and neutron electromagnetic radii and magnetic moments from lattice QCD
Miguel Salg, Dalibor Djukanovic, Georg von Hippel +3
We present results for the electromagnetic form factors of the proton and neutron computed on the -flavor Coordinated Lattice Simulations (CLS) ensembles including both qu…

Miguel Salg, Dalibor Djukanovic, Georg von Hippel +3
We present results for the electromagnetic form factors of the proton and neutron computed on the -flavor Coordinated Lattice Simulations (CLS) ensembles including both qu…
Status update: transition form factor on CLS ensembles
Jonna Koponen, Antoine Gérardin, Harvey B. Meyer +2
In this report we present the status of the Mainz group's lattice QCD calculation of the pion transition form factor, which describes the interaction of an on-shell pion with two o…
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…
Padé and Padé-Laplace Methods for masses and matrix elements
Georg M. von Hippel
The problem of having to reconstruct the decay rates and corresponding amplitudes of the single-exponential components of a noisy multi-exponential signal is common in many other a…
Nucleon Sigma Terms with O()-improved Wilson fermions
Andria Agadjanov, Dalibor Djukanovic, Georg von Hippel +3
We present a lattice-QCD based analysis of the nucleon sigma terms using gauge ensembles with flavors of -improved Wilson fermions, with a complete error…
