TITLE:   The role of renormalisation in the fine-tuning discussion            

Abstract:  The sensitivity of the Higgs sector to high-scale physics make it a prime probe for physics beyond the Standard Model. At the same time, a large hierarchy between the electroweak scale and the scale of new physics may introduce problems with the fine tuning of the Higgs boson mass. As a result, it has become a guiding principle for model building to extend the Standard Model in such a way that the fine-tuning problem is avoided. This can for instance be done by invoking additional symmetries, compositeness or extra dimensions. In this talk we will have a closer look at the role of renormalization in determining the robustness of the fine-tuning problem.
