Phenomenological aspects of flavoured dark matter [PDF]

, 2015
Flavour symmetries in the dark sector are a theoretically motivated and phenomenologically appealing concept. The dark matter particle can be stabilised with the help of flavour symmetries, without the need to introduce an additional discrete symmetry by

Simplified models of flavourful leptoquarks

European Physical Journal C: Particles and Fields, 2019
We study the implications of single leptoquark extensions of the Standard Model (SM) under the assumption that their enhanced Yukawa sectors are invariant under global Abelian flavour symmetries already present in SM mass terms.

The Interplay Between GUT and Flavour Symmetries in a Pati-Salam x S4 Model [PDF]

, 2010
Both Grand Unified symmetries and discrete flavour symmetries are appealing ways to describe apparent structures in the gauge and flavour sectors of the Standard Model. Both symmetries put constraints on the high energy behaviour of the theory.

Flavor structures of quarks and leptons from flipped SU(5) GUT with A 4 modular flavor symmetry

Journal of High Energy Physics, 2023
We propose to generate the flavor structures of the Standard Model plus neutrinos from flipped SU(5) GUT with A 4 modular flavor symmetry. Possible way to assign different moduli values for quarks and leptons in modular GUT scheme is discussed.

Neutrino masses and flavour symmetry [PDF]

Il Nuovo Cimento A, 1997
The problem of neutrino masses and mixing angles is analysed in a class of supersymmetric grand unified models, withSO(10) gauge symmetry and globalU(2) flavour symmetry. Adopting the seesaw mechanism for the generation of the neutrino masses, one obtains a mass matrix for the left-handed neutrinos which is directly related to the parameters of the ...

Non-minimally flavour violating dark matter [PDF]

, 2015
Flavour symmetries provide an appealing mechanism to stabilize the dark matter particle. I present a simple model of quark flavoured dark matter that goes beyond the framework of minimal flavour violation.

Flavourful SMEFT likelihood for Higgs and electroweak data

Journal of High Energy Physics, 2020
We perform an updated fit to LHC Higgs data and LEP electroweak precision tests in the framework of the Standard Model Effective Field Theory (SMEFT). We assume a generic structure of the SMEFT operators without imposing any flavour symmetries.

The Flavour Portal to Dark Matter

, 2015
We present a class of models in which dark matter (DM) is a fermionic singlet under the Standard Model (SM) gauge group but is charged under a symmetry of flavour that acts as well on the SM fermions. Interactions between DM and SM particles are mediated

Finite family groups for fermionic and leptoquark mixing patterns

Journal of High Energy Physics, 2020
We employ a bottom-up and model-independent technique to search for non-Abelian discrete flavour symmetries capable of predicting viable CKM and PMNS matrices alongside of special patterns of leptoquark couplings.
