Search for narrow resonances in dijet final states at the LHC with √s=13 TeV

The search for dijet resonances at the start-up of the Large Hadron Collider with a center-of-mass energy of √s = 13 TeV is one of the most simple yet powerful and promising new physics searches. Many leading theories aimed at extending the standard model predict the existence of heavy resonant states that decay into pairs of jets. This thesis presents new results from LHC operation at 13 TeV, which yield the most stringent limits yet obtained on six models, thus substantially advancing this important field.
