The CMS experiment at the Large Hadron Collider (LHC) at CERN was designed to measure precisely the properties and interactions of elementary particles in the proton-proton collisions of the LHC, the most energetic particle accelerator ever built. With the discovery of the Higgs boson at LHC in 2012, the research programme focuses on precision measurements of the electroweak sector as well as on direct searches for new phenomena such as the production of dark matter or supersymmetric particles. By comparing the experimental results to theoretical predictions, the model parameters can be determined more precisely. Observed deviations from the predictions of the Standard Model would indicate the validity limits of this very successful effective theory as well as the direction toward its extension, a more fundamental theory.

The student will join one of the ongoing research projects within the MTA-ELTE Lendület CMS Particle and Nuclear Physics Group.  They will analyse the LHC Run 2 collision data collected between 2015 and 2018 at record energy by the CMS experiment with the aim to challenge the Standard Model and glimpse at New Physics phenomena. The project will allow the student to work in an international environment, to learn the experimental methods used in particle physics experiments with complex detector systems, and to apply novel data mining and analysis techniques. The results are expected to be published in a high impact factor peer-reviewed journal by the CMS experiment.
