Implications of Decoupled New Physics

by Dr Tevong You (University of Cambridge)

If new physics is indeed decoupled from the weak scale, as experiment suggests, then this motivates an EFT approach to phenomenology. We discuss this framework and the development of a universal approach to EFT matching at one loop. Finally we explore a possible way to make decoupled new physics compatible with a natural Higgs sector in models of cosmological relaxation.
