© 2016 Author(s). With the Higgs discovery, the full Standard Model (SM) has been experimentally established, and most of its sectors accurately tested. Nevertheless, the SM deeply relies in the presence of the Higgs, a spin-zero field, whose mass term is not expected, on theoretical grounds, to be much smaller than the Planck scale. This problem of naturalness demands a modification of the SM around the weak scale, making the exploration of the TeV-energy regime a top experimental priority. In this chapter we briefly review the most well-motivated scenarios beyond the SM that can accommodate a light Higgs, mainly centering in two ideas: Supersymmetry and compositeness.
