Pheno Journal Club: ‘Powerful Yukawas’
March 26 | 12:00 - 13:00
Every Thursday at 12:00 in Grey Room 2.
Marta Fuentes (IFT), will present “Powerful Yukawas”.
We introduce a class of models where the masses of the light Standard Model fermions are due to an Effective Field Theory operator that appears beyond dimension-4 in the power counting expansion, resulting in a `Powerful Yukawa’. The effective Yukawa coupling structure is UV-completed using a collective symmetry breaking pattern in the flavour sector, which we dub `Sprouted Symmetry Breaking.’ The irreducible signature is an enhanced Higgs coupling to the light Standard Model fermions.
