Can gravitational waves tell us anything about the Hierarchy Problem?

Resumo: The 2010s have been marked by two fundamental discoveries: the detection of the Higgs boson in 2012 and the first direct detection of Gravitational Waves in 2015. On one hand, the discovery of the Higgs boson has exacerbated the so-called Hierarchy problem (i.e. the mystery of why the Higgs boson mass is so light); on the other hand, the detection of gravitational waves has opened up the possibility of probing the physics of the early universe in previously unaccessible regimes. Interestingly, these regimes can host physics related to the hierarchy problem. In the first part of the talk, I will review the physics of gravitational waves and the hierarchy problem. I will then explain possible connections between the two, and how gravitational waves can be studied to get informations about the hierarchy problem.
