英文摘要	The newly observed Xi(1620)degrees by the Belle Collaboration inspires our interest in performing a systematic study on the interaction of an antistrange meson ((K) over bar ((*))) with a strange or doubly strange ground octet baryon B (Lambda,Sigma, and Xi), where the spin-orbit force and the recoil correction are considered in the adopted one-boson-exchange model. Our results indicate that Xi(1620)degrees can be explained as a (K) over bar Lambda molecular state with I(J(P)) = 1/2(1/2(-)) and the intermediate force from s exchange plays an important role. Additionally, we also predict several other possible molecular candidates, i.e., the (K) over bar Sigma molecular state with I(J(P)) = 1/2(1/2(-)) and the triply strange (K) over bar Xi molecular state with I(J(P)) = 0(1/2(-)).
