The Standard Model (SM) of Particle Physics describes the phenomenology of fundamental interactions between all the elementary-like particles with a great experimental success. It is a gauge theory based on Quantum Field Theory (QFT) that unifies the principles of quantum mechanics and special relativity. Its cornerstone is the so-called Higgs mechanism that realizes electroweak symmetry breaking. The signature is the H-boson, whose study is at the heart of the CERN LHC experimental program.

 

Nevertheless, some fundamental questions remain open: quantum gravity, neutrino masses, dark matter/energy, gauge hierarchy/electroweak naturalness, flavor puzzle, strong CP problem, etc. There are thus many motivations to go beyond the SM.

​

​

My research interests focus on the following issues:

​

- Electroweak & Higgs Physics: Is there a fundamental origin to the Higgs field? What stabilizes the electroweak scale against the gauge hierarchy?

​

- Flavor Puzzle: What are the origins of the fermion generations and neutrino masses? Why a Yukawa hierarchy?

​

- Ultraviolet Theory: Is QFT able to describe all interactions between the elementary particles at any scales?

​

​

In particular, I am working on different scenarios to solve these issues, like extra dimensions of space, or finding new perspectives by realizing UV/IR mixing via weakly nonlocal UV-completions.
