Beyond The Standard Model At The Large Hadron Collider: From Simplified Model Constraints To Artific

The thesis is an outstanding contribution to the field of LHC result reinterpretation, combining clarity, technical innovation, and novel phenomenological insights. Through a detailed study of electroweakino searches, the author demonstrated how existing ATLAS and CMS analyses could be leveraged to refine constraints on theoretical models and data-driven model building methods. The research significantly advanced the SModelS framework, particularly in the conception of methods dedicated to a coherent combination of LHC analyses and the development of proto-modelling tools to systematically link model building with experimental anomalies. These contributions highlight the rare expertise in statistical methods and programming within theoretical physics. The author's accomplishments, including four research articles and two major conference presentations, have established his work as an important reference for new physics studies.
