The light hadron decay processes of Z b (10610)/Z b (10650) provide us a way to study their nature and decay mechanism. In this work, we evaluate the branching ratios of Z b (10610)/Z b (10650) → V P (V and P stand for light vector and pseudoscalar mesons, respectively) using an effective Lagrangian approach, in which the contributions of intermediate bottomed meson triangle loops are considered. In our calculations, the Z b (10610) and Z b (10650) are regarded as B B * + c.c. and B * B * molecular states, respectively. The predicted branching ratios of Z b (10610) → V P are about in the order of 10 −2 , while the branching ratios of Z b (10650) → V P are in the order of 10 −3 . Furthermore, the dependence of these ratios between different decay modes of Z b (10610)/Z b (10650) on the mixing η − η ′ angle θ P is investigated, which may be a good quantity for the experiments. It is hoped that the calculations here could be tested by future experiments.
