AB  - This work addresses the measurements and phenomenology of the azimuthal separation ∆ϕ<sub>12</sub> between the jets with the largest transverse momenta (p<sub>T</sub>) in multi-jet event topologies. The measurements are based on proton-proton collision data at the center-of-mass energy of 13 TeV recorded by the Compact Muon Solenoid (CMS) experiment in 2016, and correspond to an integrated luminosity of 35.9 fb<sup>−1</sup>. The measurements are performed in ranges of the leading jet transverse momentum (p<sup>max</sup><sub>T</sub>), covering the range p<sup>max</sup><sub>T</sub>  >  200 GeV. Special attention is given to the investigation of the Sudakov region 170°  <  ∆ϕ<sub>12</sub>  <  180° in inclusive 2- and 3-jet event topologies. This region characterizes nearly back-to-back jet topologies and is sensitive to contributions from soft partonic radiation. The observables are compared to theoretical predictions based on matrix element (ME) calculation at leading- and next-to-leading-order accuracy in perturbative quantum chromodynamics (pQCD) combined with parton showers (PS).
