The structure of the light antikaon-nuclear quasi-bound states is investigated with correlated Gaussian method. We perform full three- to seven-body calculations for the systems which consist of an antikaon (anti-K) and a few nucleons (N) such as anti-KNN, anti-KNNN, anti-KNNNN and anti-KNNNNNN systems without any many-body approximation and investigate how the nuclear structure is changed by...

Understanding of the structure of exotic hadrons is an important topic of the current hadron physics. The existence of many exotic hadrons, especially the XYZ particles, indicates that the internal structure of hadrons can be more complicated than the ordinary hadrons described by qqbar or qqq. For a stable shallow bound state, Weinberg has derived the model-independent relation between the...

Comparison of theoretical predictions based on a nucleon-nucleon potential with data for elastic nucleon-deuteron scattering and nucleon induced deuteron breakup reveals the importance of the three-nucleon force (3NF). Inclusion of semi-phenomenological 3NF models into calculations in many cases improves the data description. However, some serious discrepancies remain even when 3NF is...

Very recently, four candidates of the tetraneutron state were observed in the 4He(8He,8Be) reaction at RIBF [1]. While the experiment will be continued aiming at higher statistics, the confirmation of such an exotic state with a different reaction is important. We propose a pion DCX (double charge exchange) reaction to populate a tetraneutron state via the 4He(pi-,pi+) reaction. In order to...
