Bound states of image in nuclei Original Research Article

We study the binding energy and the width of the Θ+ in nuclei, associated to the KN and KπN components. The first one leads to negligible contributions while the second one leads to a sizeable attraction, enough to bind the Θ+ in nuclei. Pauli blocking and binding effects on the KN decay reduce considerably the Θ+ decay width in nuclei and medium effects associated to the KπN component also lead to a very small width, as a consequence of which one finds separation between the bound levels considerably larger than the width of the states.
