X (3872) in QCD Sum Rules
QCD spectral sum rules is used to test the nature of the meson X(3872), assumed to be an exotic fourquark(c ¯ cq ¯ q) state with JPC = 1++. For definiteness, the current proposed recently by Maiani et al [1] isused, at leading order in as, considering the contributions of higher dimension condensate...
