Abstract

Masses for the ( Q = c or b ) molecular states are systematically computed in the framework of QCD sum rules. Technically, contributions of the operators up to dimension 6 are included in operator product expansion (OPE). The numerical result 4.13 ± 0.10 GeV for agrees well with the mass 4143.0 ± 2.9 ± 1.2 MeV for Y (4 1 4 0), which supports the molecular configuration for Y (4 1 4 0).
