Abstract

In this work we analyze the 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 KN bound states are explored, finding two poles in the isoscalar J^P=(1)/(2)^- sector that can be interpreted as the experimental Λ(1405) state.
