Nucleon resonance production in $K^{+}N$ interactions

Abstract

In this work, we discuss the possibility of studying nucleon resonances in the $K^{+}N$ interactions. Based on our model calculations, it is found that the hyperon exchange plays an important role for the excitation of nucleon resonances in the $K^{+}N$ interactions. Therefore, the studies on nucleon resonance production in the $K^{+}N$ interactions can offer us valuable information about the couplings of nucleon resonances with strange particles. By selecting suitable decay channels of nucleon resonances, some reactions are also suitable to look for missing resonances.
