Exploring multi-Higgs models with softly broken large discrete symmetry groups
Ivo de Medeiros Varzielas, Igor P. Ivanov, Miguel Levy
We develop methods to study the scalar sector of multi-Higgs models with large discrete symmetry groups that are softly broken. While in the exact symmetry limit, the model has ver…
Prospects of light charged scalars in a three Higgs doublet model with symmetry
Manimala Chakraborti, Dipankar Das, Miguel Levy +2
The stringent constraints from the direct searches for exotic scalars at the LHC as well as indirect bounds from flavor physics measurements have imposed severe restrictions on the…
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…
