Multi - quark states and QCD sum rules
Dec, 1996Citations per year
Abstract:
There have been arguments about hadronic molecules, which are weakly-bound states of two or more hadrons. We investigate the possibility of some candidates (f0 (980), a0 (980), f0 (1500), f0 (1710), etc.) using QCD sum rule approach and compare our results with multiquark states in the MIT bag model. We find that f0 (1500), f0 (1710) can be good candidates for vector-vector molecule-type multiquark states.Note:
