论文摘要
本文总结了在ICHEP-2020会议期间提出的量子染色体动力学（QCD）理论上描述的强相互作用的主要实验研究。最新结果主要是在LHC的P-P碰撞中测量，分为七个广泛的主题：（i）强耦合常数$α_s（m _ {\ rm z}）的提取; （ii）将数据与固定顺序（n $^{\ rm n} $ lo）进行比较； （iii）确定Parton分布函数（PDFS）； （iv）比较重新定义的数据（n $^{\ rm n} $ ll）PQCD计算； （v）Parton淋浴和喷气子结构分析； （vi）Semihard（双方相互作用，倍年相互作用，硬衍射）和软（弹性和衍射）QCD散射； （vii）在$ \ rm e^+e^ - $和p-p碰撞中对Parton强调的研究。
This writeup summarizes the main experimental studies of the strong interaction, theoretically described by quantum chromodynamics (QCD), that were presented during the ICHEP-2020 conference. The latest results, measured mostly in p-p collisions at the LHC, are categorized in seven broad topics: (i) Extractions of the strong coupling constant $α_s(m_{\rm Z})$; (ii) Comparison of data to fixed-order (N$^{\rm n}$LO) perturbative QCD calculations; (iii) Determinations of parton distribution functions (PDFs); (iv) Comparison of data to resummed (N$^{\rm n}$LL) pQCD calculations; (v) Parton showering and jet substructure analyses; (vi) Semihard (double parton interactions, multiparton interactions, hard diffraction), and soft (elastic and diffractive) QCD scatterings; and (vii) Studies of parton hadronization in $\rm e^+e^-$ and p-p collisions.
