Higgs boson production

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-). 

Potential MSc projects in this activity include:

  1. search for production of a pair of Higgs bosons;
  2. search for additional mass peaks in the two-photon spectrum below and far above the established mass peak at 125 GeV;
  3. search for Higgs bosons in the two-photon decay channel produced in association with dark matter;
  4. precision measurement of the Higgs boson mass;
  5. 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.

You will work with fresh 13.6 TeV data taken during Run 3 (2022-25) as well as data taken during the 2015-18 run (Run 2) of the LHC at 13 TeV . You will participate in the ongoing development of the data analysis strategies (including the application of machine-learning approaches) and code, learn, further develop and apply advanced statistical techniques, and, thus, can contribute to furthering our understanding of the Brout-Englert-Higgs (mass-generating) mechanism, or test whether there is new physics beyond the SM (such as dark matter or anomalous 2-Higgs production).
