KKN and KKN Molecular States with I = 1/2, 3/2 and JP=1/2+ Studied with Three-Body Faddeev Calculations-JIA Er-WeiPANG Hou-Rong-中文期刊【掌桥科研】
@@ Using the Akalshi-Yamazaki (AY) and Hyodo-Weise (HW) effective K , N, and KN interactions, we study possible existence of K N and N molecule states with I = 1/2,3/2 and J<'R>=1/2+ by means of three-body Faddeev equations, We find that for HW potential, K N and KKN systems with I=1/2 both are bound hadron molecular states with about 10 MeV binding energy.The relativistic effects of kinetic energy are of the order of 4-5 MeV.AY potential would give larger binding energy because of overestimating N interaction strength.Although there are attractive interactions in the case of I=3/2, the interaction is too weak to bind the systems.
