dc.description.abstractDeveloped in the early 1970s, the Standard Model of particle physics has been very successful in explaining various phenomena in the universe. The Standard Model has been built by finding the right symmetry group for each of the proposed new fields. With the announcement of the discovery of the Higgs boson on July 4th in 2012, the Standard Model was completed and interest in high energy physics has grown. However, there are still open problems in explaining the structure of the universe, such as particle-antiparticle asymmetry and the hierarchy problem. Some models that extend the Standard Model to address these problems require a Z’ field, which corresponds to U(1)’ symmetry. This study explores methods to discriminate among the Standard Model and seven different Beyond Standard Models that include the Z’ boson, from its mass, angular distribution, rapidity distribution, and likelihood, using Monte Carlo simulations on proton-proton collisions at 14 TeV at ATLAS.en_US
