We present an analysis of angular distributions and correlations of the X(3872) particle in the exclusive decay mode X(3872)-->J/psipi+ pi- with J/psi-->mu+ mu-. We use 780 pb-1 of data from pp[over ] collisions at sqrt[s]=1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. We derive constraints on spin, parity, and charge conjugation parity of the X(3872) particle by comparing measured angular distributions of the decay products with predictions for different J(PC) hypotheses. The assignments J(PC)=1++ and 2-+ are the only ones consistent with the data.
我们对X(3872)粒子在X(3872)→J/ψπ⁺π⁻且J/ψ→μ⁺μ⁻的排他衰变模式中的角分布和关联进行了分析。我们使用了费米实验室Tevatron的CDF II探测器在√s = 1.96 TeV的质子-质子对撞中收集的780 pb⁻¹数据。通过将衰变产物的测量角分布与不同J(PC)假设的预测进行比较，我们得出了对X(3872)粒子的自旋、宇称和电荷共轭宇称的限制。J(PC)=1⁺⁺和2⁻⁺的赋值是仅与数据一致的赋值。
