Por Ana Arriaga (FCUL - DF).

The discovery of the Higgs boson in 2012 was a great triumph for the Standard Model of particle physics. Yet, the interplay of the Higgs field with the vacuum fluctuations leads to the naturalness problems of particle masses and vacuum density energy (cosmological constant problem). In turn, these problems are related with the hierarchy problem of the cosmological, electroweak and Planck scales. In this talk, these problems are explained and their real relevance discussed.

Short Bio: Ana Arriaga has been a professor in the Physics Department of FCUL since 1988, where she has been teaching at the undergraduate and graduate levels. Her scientific interests lie in the field of nuclear and hadronic physics, using variational Monte Carlo methods to study light nuclei and QCD functional methods to study baryons (3 valence quarks) and the deuteron (6 valence quarks).
