Description
Azimuthal correlations between the two jets with the largest transverse
momenta pT in inclusive 2-, 3-, and 4-jet events are
presented for several regions of the leading jet pT up to 4
{Te} {V}. For 3- and 4-jet scenarios, measurements of the minimum
azimuthal angles between any two of the three or four leading
pT jets are also presented. The analysis is based on data
from proton-proton collisions collected by the CMS Collaboration at a
centre-of-mass energy of 13 {Te} {V}, corresponding to an integrated
luminosity of 35.9 {fb}^{-1}. Calculations based on leading-order matrix
elements supplemented with parton showering and hadronization do not
fully describe the data, so next-to-leading-order calculations matched
with parton shower and hadronization models are needed to better
describe the measured distributions. Furthermore, we show that azimuthal
jet correlations are sensitive to details of the parton showering,
hadronization, and multiparton interactions. A next-to-leading-order
calculation matched with parton showers in the MC@NLO method, as
implemented in herwig 7, gives a better overall description of the
measurements than the powheg method.
