论文摘要
在这项工作中，我们研究了近距离QCD校正（NLO）QCD校正到$ j/ψ$相关的生产，并在非率级QCD框架内的Higgs Boson衰减中使用了底部的Quark对。从数值结果中，{我们发现过程的衰减宽度$ h \ rightArrow b+ j/ψ+ \ bar {b} $以领先顺序（LO）主要来自Fock State $^3S^{（8）} _ 1 $的贡献，并且NOLO QCD校正可显着提高衰减宽度，可在LO上获得2倍的效率。以NLO的准确性，Fock表示$^3S^{（8）} _ 1 $和$^3p^{（8）} _ j $通道给出了主要贡献，约为$ 68 \％$ $ $ $ $ $ 29 \％$ $ 29 \％$，总衰减宽度的$ j/ψ$相关的生产与nlo poptial at nlo popery的衰减宽度相关。考虑到NLO准确性的颜色八位（CO）通道的主要贡献，包容性的衰减过程$ h \ to b+j/ψ+\ b+b+x $具有在具有高能量/亮度的未来coll孔中可以找到的。} $ j/ψ$的研究与Higgs boson decay的质量相关的$ j/ψ$的研究不仅是颜色的，而且还可以造成颜色，而不是仅限于颜色的机构，但要努力工作。对希格斯玻色子的耦合与底部夸克的调查。
In this work, we investigate the next-to-leading order (NLO) QCD correction to $J/ψ$ associated production with a bottom quark pair from the Higgs boson decay within the nonrelativistic QCD framework. From numerical results, {we find that the decay width of process $H \rightarrow b+ J/ψ+\bar{b}$ at leading order (LO) mainly comes from the contribution of the Fock state $^3S^{(8)}_1$, and the NLO QCD corrections significantly enhance the decay width at LO accuracy by about 2 times. At NLO accuracy, the Fock states $^3S^{(8)}_1$ and $^3P^{(8)}_J$ channels give the main contribution, accounting for about $68\%$ and $29\%$ of the total decay width of $J/ψ$ associated production with a bottom quark pair at NLO accuracy from the Higgs boson decay, respectively. Considering the dominant contribution of color octet (CO) channels at NLO accuracy, the inclusive decay process $H\to b+J/ψ+\bar b + X$ has the potential to be found in future colliders with high energy/luminosity.} The study of $J/ψ$ associated production with a bottom quark pair from the Higgs boson decay is not only useful to study the mechanism of color-octet, but also to assist in the investigation of the coupling for the Higgs boson with the bottom quark.
