我们定义并计算了X(3872)与两个可能的量子数指定J^{PC}=1^{++},2 ^{-+}的强耦合。我们使用这些来计算J/psi共振散射到D Dbar* 的横截面。作为所得结果的一个应用,我们修正了热强子气体中J/psi吸收的计算,以应对最近在Au-Au碰撞中的RHIC观测。
We define and compute from data the strong couplings of the X(3872) with both of the possible quantum numbers assignments J^{PC}=1^{++},2^{-+}. We use these to compute cross sections for J/psi resonance scattering into D Dbar*. As an application of the results obtained we revise the calculation of the J/psi absorption in a hot hadron gas to confront with recent RHIC observations in Au-Au collisions.
