In the SHIFT project we aim to find the underlying mechanism protecting the mass of the Higgs boson from large quantum corrections. The leading correction, which arises from the top quark, can be cancelled by introducing top-quark partners to the theory.
Therefore we study possible signatures of such top partners and search for them using data from the ATLAS experiment at CERN’s Large Hadron Collider.
The project which is funded by the Knut and Alice Wallenberg Foundation, involves theorists and experimentalists from Chalmers University of Technology, Stockholm University and Uppsala University and runs over five years (2018-2022). It covers direct searches for top partners in supersymmetry and compositeness models and indirect searches via precision measurements of processes involving top quarks.
