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
