我们报道了在RHIC的恒星实验中，在p+p碰撞中，在{S}=200GeV的情况下，测量到的J/psi极化的新结果。在螺旋度和Collins-Soper(CS)参照系中，测量了偏振参数$\lambda_\theta$、$\lambda_\Phi$和$\lambda_{\theta\Phi}$，作为横向动量($p_T)的函数。除了CS标架中的$\lambda_\theta$在最高测量值$p_T$处外，所有三个偏振参数在两个参照系中都与0一致，没有任何强烈的$p_T$相关性。几个模型的计算与数据进行了比较，其中使用色玻璃凝聚有效场理论和非相对论QCD的模型给出了对实验结果的最好的总体描述，尽管由于实验的不确定性不能排除其他模型。
We report on new measurements of inclusive J/$\psi$ polarization at mid-rapidity in p+p collisions at $\sqrt{s}$ = 200 GeV by the STAR experiment at RHIC. The polarization parameters, $\lambda_\theta$, $\lambda_\phi$, and $\lambda_{\theta\phi}$, are measured as a function of transverse momentum ($p_T$) in both the Helicity and Collins-Soper (CS) reference frames within $p_T< 10$ GeV/$C$. Except for $\lambda_\theta$ in the CS frame at the highest measured $p_T$, all three polarization parameters are consistent with 0 in both reference frames without any strong $p_T$ dependence. Several model calculations are compared with data, and the one using the Color Glass Condensate effective field theory coupled with non-relativistic QCD gives the best overall description of the experimental results, even though other models cannot be ruled out due to experimental uncertainties.
