Finger on the trigger – SUSY in the focus, Learning from Run I LHC data to improve Supersymmetry searches with jets and missing transverse energy with ATLAS at the 13 TeV LHC
Antonio Strübig, promovenda aan het Nikhef, verdedigt haar proefschrift woensdag 30 mei 2018 aan de Radboud Universiteit Nijmegen.
“From early days of human development, mankind always aspired to understand its surrounding world – from the largest scales found in the universe to the tiniest particles, elementary building blocks of matter. Our current understanding of particle physics is described by the Standard Model. Particles predicted by the Standard model have been discovered over the past years since the development of the theory. Its latest success is the discovery of the Higgs Boson at the Large Hadron Collider in 2012.
Despite its stunning predictive capabilities, the Standard Model leaves some open questions. One deficit is that it describes only about 5% of the matter and energy in the universe without any explanation of the remaining 95% – so called dark matter and dark energy. Even in the description of known matter remain some unsolved problems. An elegant solution to these problems is proposed by introducing Supersymmetry. Supersymmetry postulates a partner particle for each existing particle with the same properties except the spin. It also includes a good candidate for dark matter. By doubling the number of elementary particles, Supersymmetry provides a whole zoo of new particles, they only need to be found.
The search for supersymmetry in a final state with 2-6 jets, missing transverse energy and no leptons is described in this thesis. Missing transverse energy triggers play an important role for the search and an approach using Kalman filters for this trigger leads to an trigger efficiency improvement. In addition a large scale fit of the MSSM-15 is presented that results in a best-fit point allowing to improve the existing supersymmetry searches.”
