A recent experimental analysis suggested to represent the X(3872) -resonance as a c \( \bar{{c}}\) 11 D 2 state but this attribution is being hotly debated. We calculate the mass values for that state by means of a previously studied constituent-quark model. The different contributions of the model Hamiltonian to the total mass are also explicitly shown.

On a possible interpretation of the X(3872) as a 11D2 state in a constituent-quark model based on a generalized Fermi-Breit equation
