This review provides a comprehensive summary of results on the physics of strongly
interacting matter in the presence of background electromagnetic fields, obtained via …

This is a review of hadron structure physics from lattice QCD. Throughout this report, we
place emphasis on the contribution of lattice results to our understanding of a number of …

In 2018, the USQCD Collaboration's Executive Committee organized several subcommittees
to recognize future opportunities and formulate possible goals for lattice field theory …

We determine the light meson spectrum in QCD in the presence of background magnetic
fields using quenched Wilson fermions. Our continuum extrapolated results indicate a …

Compton scattering from protons and neutrons provides important insight into the structure
of the nucleon. For photon energies up to about 300 MeV, the process can be parameterised …

The nuclear matrix element determining the pp→ de+ ν fusion cross section and the Gamow-
Teller matrix element contributing to tritium β decay are calculated with lattice quantum …

We review the current state of knowledge of the nucleon polarizabilities and of their role in
nucleon Compton scattering and in hydrogen spectrum. We discuss the basic concepts, the …

Lattice QCD calculations of two-nucleon systems are used to isolate the short-distance two-
body electromagnetic contributions to the radiative capture process np→ d γ, and the photo …

The Feynman-Hellmann theorem can be derived from the long Euclidean-time limit of
correlation functions determined with functional derivatives of the partition function. Using …

We study low-energy nucleon Compton scattering in the framework of baryon chiral
perturbation theory (B χ PT) with pion, nucleon, and Δ (1232) degrees of freedom, up to and …
