Theoretical particle physics

Welcome to our group!

Our group tackles the central problems left open by the Standard Model. We build and test theories that explain why electroweak symmetry breaks the way it does, why the Higgs mass is stable, and how these issues connect to flavour, CP violation, and the early Universe.

Electroweak dynamics. We explore mechanisms—composite Higgs, symmetry protection, cosmic phase transitions—that stabilise the electroweak scale and predict signals for the LHC upgrade and future colliders. Extreme astrophysical environments serve as complementary laboratories, where dense matter can unlock new effects to  completely change the appearance of neutron stars and white dwarfs.

Dark matter. We study their dark matter production in the early Universe, their imprint on stellar evolution and structure formation, and the subtle ways they evade current detectors while remaining testable by forthcoming experiments and surveys.

Gravity as an EFT. We formulated a complete effective field theory of Einstein gravity coupled to the full Standard Model. This GR + SM EFT lets us track quantum corrections, derive constraints from amplitudes and positivity, and identify where deviations from General Relativity could appear—in gravitational waves, precision tests, or cosmology.

Across these themes, we target phenomena that next-generation data can confirm or rule out. By combining particle theory, cosmology, and gravitational physics, we search at the frontiers of fundamental science and map promising routes to new physics.
