Abstract This White Paper presents an overview of the current status and future perspective
of QCD research, based on the community inputs and scientific conclusions from the 2022 …

Electromagnetic polarizabilities are fundamental properties of the proton that characterize its
response to an external electromagnetic (EM) field. The generalization of the EM …

We present the first ab initio calculation of elastic Compton scattering from 4 He. It is carried
out to O (e 2 δ 3)[N 3 LO] in the δ expansion of χ EFT. At this order and for this target, the …

The proton charge radius and nucleon electromagnetic polarizabilities are fundamental
properties probing the electromagnetic structure of the nucleons. Proton charge radius is …

A new data set for the helicity-dependent differential cross section of the single-meson
photoproduction reaction $\gamma p\to p\pi^{0} $ was obtained for the photon energy …

It is currently understood that there are four fundamental forces in nature: gravitational,
electromagnetic, weak and strong forces. The strong force governs the interactions between …

A new data set for the helicity-dependent differential cross section of the single-meson
photoproduction reaction γ p→ p π 0 was obtained for the photon energy interval 150–400 …
