Not your normal SUSY talk: statistical combinations and reuse of electroweak searches

Dr. Giordon Stark
Postdoctoral Researcher

Searches for new physics at the Large Hadron Collider have constrained many models of physics beyond the Standard Model. It has become more possible to search for Supersymmetry (SUSY) through electroweak interactions, the production of electroweakinos and sleptons, noted for their low cross sections. In addition, due to the high dimensionality of the phenomenological models, it is difficult to cover the landscape of new physics predicted by SUSY. This talk will introduce two different ATLAS analyses targeting simplified models and the unique techniques developed to explore challanging phase-spaces. After an overview of these state-of-the-art results from ATLAS, I will show how we extend existing constraints on these simplified models through statistical combinations. The results of the combination will remain the strongest limits set on electroweak SUSY production for the better part of this decade. Finally, this talk will wrap up with a brief overview of a reinterpretation pipeline (mapyde) that can be used both as a pedagogical tool as well as a tool to explore new models outside of the experimental collaborations. Using this tool, I will motivate some potential directions for new physics searches.
