论文摘要

我们计算了颜色单词和颜色octet非递归QCD(NRQCD)长距离矩阵元素,用于在潜在的NRQCD框架内包含$ p $ - 波Quarkonia。通过这种方式,可以在不依赖测量的横截面数据的情况下确定颜色octet nrqcd长距离矩阵元素,到目前为止还不可能。我们在LHC上获得了$χ_{CJ} $的包含横截面和$χ_{BJ} $,这与数据非常吻合。原则上,这封信中开发的形式主义可以应用于所有重型Quarkonia的包容性生产过程。

We compute the color-singlet and color-octet nonrelativistic QCD (NRQCD) long-distance matrix elements for inclusive production of $P$-wave quarkonia in the framework of potential NRQCD. In this way, the color-octet NRQCD long-distance matrix element can be determined without relying on measured cross section data, which has not been possible so far. We obtain inclusive cross sections of $χ_{cJ}$ and $χ_{bJ}$ at the LHC, which are in good agreement with data. In principle, the formalism developed in this Letter can be applied to all inclusive production processes of heavy quarkonia.
