Symmetries and stabilisers in modular invariant flavour models
Ivo de Medeiros Varzielas, Miguel Levy, Ye-Ling Zhou
The idea of modular invariance provides a novel explanation of flavour mixing. Within the context of finite modular symmetries and for a given element , we present…

Crossed two Higgs-doublet models: reduction of Yukawa parameters in the low-scale limit of left-right symmetry and other avatars
Gustavo C. Branco, Dipankar Das, Miguel Levy +1
We present new variants of the Two Higgs-Doublet Model where all Yukawa couplings with physical Higgs bosons are controlled by the quark mixing matrices of both chiralities, as wel…

Effective alignments and the landscape of flavour models
Ivo de Medeiros Varzielas, Miguel Levy, Ye-Ling Zhou
We explore the concept of effective alignments: contractions of multiple flavour symmetry breaking flavon fields. These contractions give rise to directions that are hard or imposs…
