Two charged states have been seen in the hidden-beauty sector, dynamics, rather than in a molecular picture.2 Indeed, some models based on quark dynamics have predicted the isospin I = 1 state The aim of this article is to revisit how the isospin I = 1 partner of the X (3872) was predicted in a simple model [19], and to where the mi are effective quark masses including the chromoelectric effects, and λ̃i and σ i the colour and spin operator acting The difficulty in our model (1) consists in identifying a single effective mass for a flavoured quark in open-flavour mesons, Parameters of the model: masses mi , non-vanishing chromoelectric Ai j and chromomagnetic C i j coefficients (in MeV). Masses or mass differences of ground state hadrons in the model (in GeV).	./cache/work_hqijlvnozjhphpjthlwvhteate.pdf	./txt/work_hqijlvnozjhphpjthlwvhteate.txt
