Description
The so-called "Hierarchy Problem" is one of the main driving forces behind the
nowadays exploration of physics beyond the Standard Model (BSM). In its simplest
form, the Hierarchy Problem asks why the weak interaction is $\sim 10^{30}$ times
stronger than gravity. The goal of this presentation is to state the body of the
problem in a precise yet accessible manner, with a particular emphasis on the
concept of symmetry in particle physics. Afterwards, I will briefly discuss how
this problem can be solved in various BSM theories, such as Supersymmetry,
Compositeness and Extra Dimensions.
