Decay constant

Summary Experiments are discovering (candidates of) exotic mesons. Quark-gluon mixed condensate is encoded in the hard wall model Predicted mass and decay constant of Pi1(1400) are reasonable. What about charmed tetra-quark mesons in hQCD? ~ 4.83 GeV for a vector state [Kyung-il Kim, YK, S. H. Lee, in progress].
