| Abstract: Multijet events at large transverse momentum ($p_{\mathrm{T}}$) are measured at $\sqrt{s}= $ 13 TeV with 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 in addition to a high $p_{\mathrm{T}}$ dijet system is measured for different regions of the transverse momentum of the leading $p_{\mathrm{T}}$ jet and as a function of the azimuthal angle $\Delta\phi_{1,2}$ between the two leading jets in the dijet system. The differential cross section of the four jets leading in $p_{\mathrm{T}}$ is measured as a function of their transverse momentum. The measurements are compared to leading order matrix-element calculations supplemented with parton shower, hadronization and multiparton interactions. In addition next-to-leading order matrix-element calculations combined with conventional parton shower as well as with Parton Branching (PB) transverse momentum dependent (TMD) parton densities and PB-TMD initial state parton shower are compared to the measurements. | ||
