Abstract
A selection of recent experimental results on jet measurements in proton-proton collisions at $\sqrt{s}$ = 13 TeV from the CMS Collaboration is presented. Differential measurements of the inclusive jet and dijet production cross sections are performed as a function of transverse momentum ($p_{\rm T}$) and absolute rapidity, and the impact of these data on determinations of the strong coupling constant and the parton distribution functions is presented. In addition, a measurement of jet multiplicity and $p_{\rm T}$ in multijet events is outlined and compared to predictions obtained for different parton shower models and with various Monte Carlo (MC) event generators. Finally, a measurement of the Lund jet plane density, which represents the phase space of emissions inside jets, is described, and the results are compared to predictions obtained from MC generators with different tunes, parton showers and hadronization models.
