Abstract

In this work we analyze the $\bar KN$ interaction in the framework of a constituent quark model. The near-threshold elastic and charge exchange cross sections are evaluated, finding a good agreement with the experimental data. Furthermore, the possible existence of $\bar KN$ bound states are explored, finding two poles in the isoscalar $J^P=\frac{1}{2}^-$ sector that can be interpreted as the experimental $\Lambda(1405)$ state.
