Non-standard Higgs Signals and Physics at Shorter Distance

There is strong evidence that new phenomena are associated with shorter distance scales than the ones probed so far. Beginning in March, collider experiments at unprecedented high energies will explore these phenomena for more than a decade. The first layer of new physics that will be unraveled is expected to shed light on the origin of electroweak symmetry breaking. From this perspective, it is paramount to establish whether a Higgs boson exists, and if so what are its properties. I will discuss the leading candidates among theories with a Higgs boson, and show that each of them allows for highly non-standard Higgs decays. The study of these signals may point to marvelous phenomena beyond the standard model, such as supersymmetry, strongly-coupled dynamics, or extra spatial dimensions.
