Lattice QCD calculation of the Compton amplitude subtraction function
K. U. Can, A. Hannaford-Gunn, R. Horsley +6
The Compton amplitude subtraction function is an essential component in work concerning both the proton radius puzzle and the proton-neutron mass difference. However, owing to the…
Lattice QCD evaluation of the Compton amplitude employing the Feynman-Hellmann theorem
K. U. Can, A. Hannaford-Gunn, R. Horsley +8
The forward Compton amplitude describes the process of virtual photon scattering from a hadron and provides an essential ingredient for the understanding of hadron structure. As a…
Electromagnetic contribution to - mixing using lattice QCD+QED
Z. R. Kordov, R. Horsley, Y. Nakamura +6
Mixing in the - system is a direct consequence of broken isospin symmetry and is a measure of both isospin-symmetry breaking as well as general SU(3)-flavour symmetry bre…
Isospin splittings in the decuplet baryon spectrum from dynamical QCD+QED
R. Horsley, Z. Koumi, Y. Nakamura +8
We report a new analysis of the isospin splittings within the decuplet baryon spectrum. Our numerical results are based upon five ensembles of dynamical QCD+QED lattices. The analy…
Electroproduction of the N*(1535) resonance at large momentum transfer
V. M. Braun, M. Göckeler, R. Horsley +11
We report on the first lattice calculation of light-cone distribution amplitudes of the N*(1535) resonance, which are used to calculate the transition form factors at large momentu…
Hadronic structure from the lattice
Dirk Brommel, Meinulf Gockeler, Philipp Hagler +10
In recent years the investigation of hadron structure using lattice techniques has attracted growing attention. In this talk we give an overview on recent work with a focus on resu…
