Z c s + production in B + decays

Year: 2025

Type: article

Abstract: In the present work, we study the Z c s + exotic state production in the B + meson decays through the meson loop mechanism, where the B + meson decays into an anticharmed meson and a charmed-strange meson pair, and consequently couples to Z c s and a light meson ( ϕ , ρ 0 , ω , η , η ′ , and π 0 ) via exchanging a proper charmed or charmed-strange meson. Using the effective Lagrangian approach, we estimate the branching fractions of different channels, finding them to be of the order of 10 − 4 , and their ratios are almost independent of the model parameter. The fit fractions of Z c s + in different B + decay processes are also estimated, and we propose searching for Z c s + in the B + → J / ψ K + η ′ process, which should be accessible to both Belle II and LHCb Collaborations.
