A note on the B*B̄, B*B̄*, D*D̄, D*D̄* molecular states

Abstract

In the framework of the one-boson-exchange model, we have performed an extensive study of the possible B*B̄, B*B̄*, D*D̄, D*D̄* molecular states with various quantum numbers after considering the S-wave and D-wave mixing. We also discuss the possible experimental research of these interesting states.

The hidden-charm pentaquark and tetraquark states

“…[204], respectively. Their hidden-charm partners were also predicted, which can be related to the Z c (3900) [205].…”

“…The authors of Refs. [205,243,467] noticed that it is not so easy to accommodate Z c (3900) as an isovector DD * molecular bound state, which is supported by several Lattice studies [468,469,470,471]. Prelovsek and Leskovec searched for the Z c (3900) on the lattice in the channel with J PC = 1 +− and I = 1 without success [468].…”

“…[205] performed an extensive study of the possible B * B , B * B * , D * D , D * D * molecule states in the framework of the OBE model. They considered neutral and charged DD * modes and S-wave and D-wave mixing.…”

“…Many dynamical studies suggested that the D and D * interaction is strongly attractive [197,543,548,220,549,226,223,205,241,243]. Hence, a pure χ c1 (2P) with J PC = 1 ++ can easily couple to the S -wave DD * scattering state if their masses are similar.…”

“…Interpretations in terms of tetraquarks, molecules, hadrocharmonium, and cusp effects have been proposed [11][12][13][14][15][16][17][18][19]. Searching for their neutral partners in experiments is of great importance in understanding their properties, especially for identifying their isospin properties.…”
