The nuclear-physics landscape has been redesigned as a sequence of effective field
theories (EFTs) connected to the standard model through symmetries and lattice simulations …

We review the structure of Roy–Steiner equations for pion–nucleon scattering, the solution
for the partial waves of the t-channel process π π→ N ̄ N, as well as the high-accuracy …

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 with background magnetic fields is used to calculate the magnetic moments
and magnetic polarizabilities of the nucleons and of light nuclei with A≤ 4, along with the …

We present a lattice QCD calculation of the nucleon electric polarizabilities at the physical
pion mass. Our findings reveal the substantial contributions of the N π states to these …

The difference between the electromagnetic self-energies of proton and neutron can be
calculated with the Cottingham formula, which expresses the self-energies as an integral …

Interpreting measurements requires a physical theory, but the theory's accuracy may vary
across the experimental domain. To optimize experimental design, and so to ensure that the …

We update the predictions of the SU (2) baryon chiral perturbation theory for the dipole
polarisabilities of the proton,{α _ E1,\, β _ M1\} _p={11.2 (0.7),\, 3.9 (0.7)\} * 10^-4 α E 1, β M …

Phenomenological amplitudes obtained in partial-wave analyses (PWA) of single-pion
photoproduction are used to evaluate the contribution of this process to the Gerasimov-Drell …

Conventional hadron interpolating fields, which utilize gauge-covariant Gaussian smearing,
are ineffective in isolating ground state nucleons in a uniform background magnetic field …
