摘要To validate the molecular description of the observed Z(b)(10610)/Z(b)(10650) and Z(c)(3900)/Z(c)(4025), it is valuable to investigate their counterparts, denoted as Z(QV)(()'()) in this work, and the corresponding decay modes. In this work, we present an analysis of the Z(QV)(()'()) using flavor symmetry. We also use the effective Lagrangian based on the heavy quark symmetry to explore the rescattering mechanism and calculate the partial widths for the isospin conserved channels Z(QV)(()'()) -> eta V-Q. The predicted partial widths are of an order of MeV for Z(QV) -> eta V-Q which corresponds to branching ratios of the order 10(-2) similar to 10(-1). For Z(QV)' -> eta V-Q, the partial widths are a few hundreds of keV and the branching ratios are about 10(-3). Future experimental measurements can test our predictions on the partial widths and thus examine the molecule description of heavy quarkoniumlike exotic states.
