Unveiling New Physics through Angular Distributions in Dilepton and Diboson Final States at the LHC

This thesis focuses on searches for new physics effects using angular distributions in particle colliders. In particular, angular distributions in dilepton and diboson final states have been studied. Two type of new physics effects have been searched for: 1. Small deviations in dilepton distributions due to the presence of quantum interference effects involving dark matter particles, and 2. Signals from exotic heavy resonances in the rapidity distributions of Wgamma production.
