| Abstract: We investigate collinear and wide-angle as well as soft and hard radiation in multijet and Z+2 jet events collected in pp collisions at the LHC. We measure the transverse momentum ratio of the two jets and the angular separation between them. The measurements use 19.8 fb$^{-1}$ and 2.29 fb$^{-1}$ of data collected by the CMS experiment at the center-of-mass energies of 8 and 13 TeV, respectively. The data are compared to theoretical predictions from event generators, including parton showers, multiparton interactions, and hadronization. We observe that the collinear and soft regions are in general well described by parton showers, while the regions of large angle separation are often better described by calculations using higher order QCD matrix elements. | ||
