Threshold corrections of χc(2P) and χb(3P) states and J/ψρ and J/ψω transitions of the X(3872) in a coupled-channel model
We calculate the masses of χc(2P) and χb(3P) states with threshold corrections in a coupled-channel model. Here, the meson quarkonium core is augmented by higher Fock components due to pair-creation effects. According to our results, we interpret the resonances characterized by very small threshold...
