Abstract
A measurement of inclusive four-jet production in proton-proton collisions at
a center-of-mass energy of 13 TeV is presented. The transverse momenta of jets within
|η| < 4.7 are required to exceed 35, 30, 25, and 20 GeV for the first-, second-, third-, and
fourth-leading jet, respectively. Differential cross sections are measured as functions of the
jet transverse momentum, jet pseudorapidity, and several other observables that describe
the angular correlations between the jets. The measured distributions show sensitivity
to different aspects of the underlying event, parton shower modeling, and matrix element
calculations. In particular, the interplay between angular correlations caused by parton
shower and double-parton scattering contributions is shown to be important. The doubleparton scattering contribution is extracted by means of a template fit to the data, using
distributions for single-parton scattering obtained from Monte Carlo event generators and
a double-parton scattering distribution constructed from inclusive single-jet events in data.
The effective double-parton scattering cross section is calculated and discussed in view of
previous measurements and of its dependence on the models used to describe the singleparton scattering background
