| contents | In the present work, we studied the $Z_{cs}^+$ exotic state production in the $B^+$ meson decays through the meson loop mechanism, where the $B^+$ meson decays into an anti-charmed meson and a charmed-strange meson pair, and consequently couples to $Z_{cs}$ and a light meson ($ϕ,ρ^0,ω,η,η^\prime$, and $π^0$) via exchanging a proper charmed or charmed-strange meson. Using the effective Lagrangian approach, we estimated the branching fractions of different channels find them to be on the order of $10^{-4}$ and their ratios are almost independent of the model parameter. The fit fractions of $Z_{cs}^+$ in different $B^+$ decay processes are also estimated, and we propose searching for $Z_{cs}^+$ in the $B^+ \to J/ψK^+η^\prime$ process, which should be accessible to both Belle II and LHCb Collaborations. |
