Higgs boson production

Although the first measurements of the properties of the Higgs boson discovered at CERN in 2012 are consistent with the Standard Model (SM), the uncertainties are large and there are many physically motivated models that would give small deviations from the SM predictions. The group in Oslo works on the decay channel of the Higgs boson to two photons.

Potential MSc projects in this activity include:

  1. the study of robust statistical models for the data-driven estimation of the background under the Higgs boson signal peak in the two-photon mass spectrum;
  2. development of a procedure to optimize the use of computing-intensive detailed simulations of the detector;
  3. search for additional mass peaks below and far above the established mass peak at 125 GeV;
  4. precision measurement of the Higgs boson mass.

You will work with data taken during the 2015-18 runs of the LHC at 13 TeV, nearly twice the center of mass energy compared to 2011-12 (7 and 8 TeV). You will join the Hgamma working group in ATLAS, participate in the ongoing development of the data analysis strategies and code, learn, further develop and apply advanced statistical techniques, and, thus, contribute to furthering our understanding of the Brout-Englert-Higgs (mass-generating) mechanism and test whether there is new physics beyond the SM (such as dark matter).
