Description

The Standard Model (SM) of Particle Physics provides an excellent description of nature. However, it is very much an empirical model: Why are there 3 generations of matter with such large mass hierarchies? What is the origin of their mixings? What is dark matter (DM)? What dynamics govern the Higgs mechanism? If Ultraviolet symmetry breaking governs the structure we observe at the weak scale, apparent fine-tunings may be a hint of the global structure dictating beyond the SM physics. In this talk I will discuss some fine-tunings that may be responsible for the structure we observe in Higgs couplings, fermion masses and mixings, and possible connections of the Higgs sector with DM.
