Abstract
Multijet events at large transverse momentum (

) are measured at
$$\sqrt{s}=13\,\text {TeV} $$

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.
