Do new fundamental forces show up at the LHC the way the Z and Higgs bosons did? According to superstring theories, which propose to unify all fundamental forces, including gravity, there is room for new forces to be mediated by new gauge bosons, known as Z’ and W’. The W’ boson is also predicted by theories aiming at restoring parity (left-right) symmetry at high energies. This work consists of: (i) a detailed study and implementation into MC generators of various theories beyond the SM, (ii) an analysis of ATLAS data, taken at the highest available energies, and a comparison to simulation data. You will make use of one of the following processes:

Although the current measurements of the properties of the Higgs boson discovered at CERN in 2012 are consistent with the Standard Model (SM), the uncertainties are still large enough to be consistent with many physically motivated models that would give small deviations from the SM predictions. In addition, the SM predicts, with a very small rate, the production of pairs of Higgs bosons. The group in Oslo has experience with the decay channels of the Higgs boson to two photons and two charged weak bosons (W+W-).
