主 题:molecular states QCD sum rules
摘 要:In this article, we assign the Y(4390) and Y(4220) to be the vector molecular states D1(2420) and D* *0(2400), respectively, and study their masses and pole residues in detail with the QCD sum rules. The present calculations only favor assigning the Y(4390) to be the D1(1^--) molecular state.
