Search for New Physics in Dijet Angular Distributions in Proton-Proton Collisions at 13 TeV

High momentum-transfer proton-proton collisions at the CERN Large Hadron Collider probe the dynamics of the underlying interaction at distances down to 10-20 m. These collisions predominantly produce events containing two jets with high transverse momenta. Studies of these events allow us to probe the dynamics of the underlying interactions and can be used to test the predictions of perturbative quantum chromodynamics and to search for signatures of new physics beyond the standard model of particle physics. Measurements of dijet angular distributions from proton-proton collisions at a center-of-mass energy of 13 TeV using data collected in 2016 by the Compact Muon Solenoid experiment are presented. These measurements are used to constrain models containing quark contact interactions, extra spatial dimensions, quantum black holes, and dark matter.
