Theories of flavour from the Planck scale to the electroweak scale
Theories of flavour from the Planck scale to the electroweak scale
The flavour puzzle remains as one of the most intriguing enigmas of particle physics. In this thesis, we propose and study theories of flavour which generically hint to a multi-scale origin of flavour. First we explore the idea of fermiophobic models and messenger dominance, where the chiral fermions of the …
