Title: P-wave [cs][cs] tetraquark state: Y(4260) or Y(4660)?

Abstract

The mass of a P-wave cs-scalar-diquark cs-scalar-antidiquark state is computed in the framework of QCD sum rules. The result 4.69{+-}0.36 GeV is in good agreement with the experimental value of Y(4660) but higher than Y(4260)'s, which supports the P-wave [cs][cs] configuration for Y(4660) while disfavors the interpretation of Y(4260) as the P-wave [cs][cs] state. In the same picture, the mass of P-wave [bs][bs] is predicted to be 11.19{+-}0.49 GeV.
