A Rationale for Long-lived Quarks and Leptons at the LHC: Low Energy Flavour Theory [PDF]

, 2011
In the framework of gauged flavour symmetries, new fermions in parity symmetric representations of the standard model are generically needed for the compensation of mixed anomalies.

Modular A5 symmetry for flavour model building [PDF]

Journal of High Energy Physics, 2019
Abstract In the framework of the modular symmetry approach to lepton flavour, we consider a class of theories where matter superfields transform in representations of the finite modular group Γ5 ≃ A 5. We explicitly construct a basis for the 11 modular forms of weight 2 and level 5.

Generation of SU(3) sum rule for charmed baryon decay

Journal of High Energy Physics, 2022
Flavor SU(3) symmetry is a powerful tool to analyze charmed baryon decays. In this work, we propose an approach to generate SU(3) sum rules for the singly and doubly charmed baryon decays without writing the Wigner-Eckhart invariants explicitly. The SU(3)

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.

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.

The interplay between grand unified and flavour symmetries in a Pati-Salam x S4 model [PDF]

, 2010
Both discrete flavour symmetries and Grand Unified symmetries explain apparent structures in the mass sector of the Standard Model. A model that combines both symmetries is therefore very appealing.
