Two- and three-body resonances in the $ar{K}$NN − πΣN system

One of the most important characteristics of a two-body interaction is existence and properties of its bound states or resonances. When the interaction is used in a few- or many-body calculation they also strongly inﬂuence the properties of the few- or many-body system. We investigate the depende...
