论文摘要
大型横向动量（$ p_ \ mathrm {t} $）处于$ \ sqrt {s} $ = 13 TEV的测量，使用LHC的CMS检测器记录的数据，对应于36.3 fb $^{ - 1} $。用$ p_ \ mathrm {t} $> $ 50 GEV与高$ p_ \ p_ \ mathrm {t} $ dijet System相关联的Jets的多样性，以$ p_ \ mathrm rm的各种范围测量，与横向动量和A $ 1 $ a $ a $ a $ a $ a $ a的范围均以$ p_ \ mathrm rm的范围为准。 Dijet系统中的两个最高$ P_ \ MATHRM {T} $喷气机。差分生产横截面的测量是四个最高$ p_ \ mathrm {t} $ jets的横向动量的函数。将测量值与补充有Parton淋浴，强膦和倍度相互作用的模拟的领先和次领先顺序矩阵元素计算进行了比较。此外，将测量值与近代领先的矩阵元素计算进行比较，结合了横向巨型依赖的parton密度和横向依赖性的parton淋浴。
Multijet events at large transverse momentum ($p_\mathrm{T}$) are measured at $\sqrt{s}$ = 13 TeV using data recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 36.3 fb$^{-1}$. The multiplicity of jets with $p_\mathrm{T}$ $>$ 50 GeV that are produced in association with a high-$p_\mathrm{T}$ dijet system is measured in various ranges of the $p_\mathrm{T}$ of the jet with the highest transverse momentum and as a function of the azimuthal angle difference $Δϕ_{1,2}$ between the two highest $p_\mathrm{T}$ jets in the dijet system. The differential production cross sections are measured as a function of the transverse momenta of the four highest $p_\mathrm{T}$ jets. The measurements are compared with leading and next-to-leading order matrix element calculations supplemented with simulations of parton shower, hadronization, and multiparton interactions. In addition, the measurements are compared with next-to-leading order matrix element calculations combined with transverse-momentum dependent parton densities and transverse-momentum dependent parton shower.
