Azimuthal separation in nearly back-to-back jet topologies in inclusive 2-and 3-jet events in pp collisions at root s=13TeV
A measurement for inclusive 2- and 3-jet events of the azimuthal correlation between the two jets with the largest transverse momenta, Δφ12, is presented. The measurement considers events where the two leading jets are nearly collinear (“back-to-back”) in the transverse plane and is performed fo...

description |
A measurement for inclusive 2- and 3-jet events
of the azimuthal correlation between the two jets with the
largest transverse momenta, Δφ12, is presented. The measurement considers events where the two leading jets are
nearly collinear (“back-to-back”) in the transverse plane and
is performed for several ranges of the leading jet transverse
momentum. Proton-proton collision data collected with the
CMS experiment at a center-of-mass energy of 13 TeV and
corresponding to an integrated luminosity of 35.9 fb−1 are
used. Predictions based on calculations using matrix elements at leading-order and next-to-leading-order accuracy in
perturbative quantum chromodynamics supplemented with
leading-log parton showers and hadronization are generally
in agreement with the measurements. Discrepancies between
the measurement and theoretical predictions are as large as
15%, mainly in the region 177◦ < Δφ12 < 180◦. The 2- and
3-jet measurements are not simultaneously described by any
of models. |
