I conduct research in particle physics within the ATLAS experimentet at CERN's Large Hadron Collider (LHC). My focus is on searching for extensions of the Standard Model that can explain the dark matter in the universe and the fine-tuning problem of the Higgs boson mass. I focus primarily on the supersymmetric parter of the top quark. Since 2018 I lead the SHIFT-project, a five year project funded by the Knut och Alice Wallenberg foundation where we develop and search for models with top quark partners with the aim of solving the Higgs fine-tuning problem.
This project aims at developing a new class of experimental probes for new Higgs-like spin-0 particles with the ATLAS experiment at LHC, and to interpret the experimental results in complete models that predict primordial Gravitational Waves (GW).
In the Standard Model, the mass of the Higgs boson is greatly destabilised by quantum corrections, and free parameters of the model need to be extremely fine-tuned in order to arrive at the measured Higgs mass.
