Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

We review how nuclear forces emerge from low-energy QCD via chiral effective field theory.
The presentation is accessible to the non-specialist. At the same time, we also provide …

We introduce new semilocal two-nucleon potentials up to fifth order in the chiral expansion.
We employ a simple regularization approach for the pion exchange contributions which i) …

We present improved nucleon-nucleon potentials derived in chiral effective field theory up to
next-to-next-to-next-to-leading order. We argue that the nonlocal momentum-space …

As Phillipson warned,“[l] inguistic imperialism [is] alive and kicking” and has become even
more subtle in an era when English has become the global lingua franca. With this, this …

Effective field theory allows for a systematic and model-independent derivation of the forces
between nucleons in harmony with the symmetries of quantum chromodynamics. The …

We present the first nucleon-nucleon potential at next-to-next-to-next-to-leading order (fourth
order) of chiral perturbation theory. Charge dependence is included up to next-to-leading …

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 …

This article provides a pedagogical introduction to the basic concepts of chiral perturbation
theory and is designed as a text for a two-semester course on that topic. Section 1 serves as …

It is often assumed that few-and many-body systems can be accurately described by
considering only pairwise two-body interactions of the constituents. We illustrate that three …
