    Signatures of three-nucleon interactions in few-nucleon systems

    N. Kalantar-Nayestanaki🇳🇱 · E. Epelbaum🇩🇪 · J.G. Messchendorp🇳🇱 · A. Nogga🇩🇪

    Recent experimental results in three-body systems have unambiguously shown that calculations based only on nucleon-nucleon forces fail to accurately describe many experimental observables and one needs to include effects which are beyond the realm of the two-body potentials. This conclusion owes its significance to the fact that experiments and calculations can both be performed with a high accuracy. In this review, both theoretical and experimental achievements of the past decade will be underlined. Selected results will be presented. The discussion on the effects of the three-nucleon forces is, however, limited to the hadronic sector. It will be shown that despite the major successes in describing these seemingly simple systems, there are still clear discrepancies between data and the state-of-the-art calculations.

    Dressed-quarks and the Roper resonance

    Craig D. Roberts🇺🇸 · Ian C. Cloet🇺🇸 · Lei Chang🇺🇸 · Hannes L.L. Roberts🇺🇸

    A Dyson-Schwinger equation calculation of the light hadron spectrum, which correlates the masses of meson and baryon ground- and excited-states within a single framework, produces a description of the Roper resonance that corresponds closely with conclusions drawn recently by EBAC. Namely, the Roper is a particular type of radial excitation of the nucleon's dressed-quark core augmented by a material meson cloud component. There are, in addition, some surprises.
