Final Report Abstract

The project on Parameter Determination at the LHC has in the last few years developed many new facets and applications. During Run I the Higgs coupling analysis was one of the key measurements of ATLAS and CMS, and we were able to contribute to the development of the method, while still providing our own fit results. The analysis of physics beyond the Standard Model benefits from these Higgs observables as well as from different anomalies at the LHC or in dark matter searches. It will gain more momentum during Run II, when the experimental analyses come closer to the heart of our preferred parameter space, for example in supersymmetric models.
