英文摘要	With the new measurements of X (3872 )→J /ψ π⁺π^- from LHCb Collaboration, in addition to the dominant contribution from the ρ⁰ meson, we perform a theoretical study on the contribution of ω meson in the X (3872 )→J /ψ π⁺π^- and X (3872 )→J /ψ π⁺π^-π⁰ processes. For the X (3872 )→J /ψ π⁺π^- decay, in addition to the main contribution from ρ⁰ meson, we consider also the X (3872 )J /ψ ω coupling with ω meson decaying directly into π⁺π^-. It is found that the recent experimental measurements on the π⁺π^- invariant mass distributions can be well reproduced, and the ratio of the couplings between X (3872 )→J /ψ ρ⁰ and X (3872 )→J /ψ ω is also evaluated. Within the parameters extracted from the π⁺π^- invariant mass distributions of the X (3872 )→J /ψ π⁺π^- process, the branching fractions of the X (3872 )→J /ψ ω channel relative to that of the X (3872 )→J /ψ π⁺π^-π⁰ channel and the π⁺π^-π⁰ invariant mass distributions of the X (3872 )→J /ψ π⁺π^-π⁰ decay are calculated, which gives a hint for the further high-statistic experiment.
