Analysis of the X(3960) and related tetraquark molecular states via the QCD sum rules
Abstract In this work, we study the $$D\bar{D}$$ D D ¯ , DD, $$D\bar{D}_s$$ D D ¯ s , $$DD_s$$ D D s , $$D_s\bar{D}_s$$ D s D ¯ s and $$D_sD_s$$ D s D s tetraquark molecular states with the $$J^{PC}=0^{++}$$ J PC = 0 + + via the QCD sum rules. The prediction $$M_{D_s\bar{D}_s} = 3.98\pm 0.10\, \text...
