Precision measurements of Higgs boson production in the decay channel to two photons in the ATLAS experiment at the Large Hadron Collider: Although the first measurements of the properties of the Higgs boson discovered at CERN in 2012 are consistent with the Standard Model, the uncertainties are large and there are many physically motivated models that would give small deviations from the Standard Model predictions. MSc projects in this activity include:
- 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;
- development of a new method to optimize the use of compute- intensive detailed simulations of the detector, (c) search for additional mass peaks below and far above the established mass peak at 125 GeV;
- precision measurement of the Higgs boson mass; and
- measurement of the transverse momentum spectrum of the Higgs boson.
You will work with data taken during Run 2 (2015-2018) of the LHC. 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 Standard Model (e.g. dark matter).
