Towards Testable Theories with Discrete Flavour Symmetries [PDF]

, 2012
The leptonic mixing matrix may be understood as a consequence of remnant symmetries of the mass matrices, which emerge from the spontaneous breakdown of a larger symmetry into smaller non-commuting subgroups. The mixing patterns that may be obtained from

Lepton-flavour-violating tau decays from triality [PDF]

, 2023
Motivated by flavour symmetry models, we construct theories based on a low-energy limit featuring lepton flavour triality that have the flavour-violating decays $\tau^\pm \to \mu^\pm \mu^\pm e^\mp$ and $\tau^\pm \to e^\pm e^\pm \mu^\mp$ as the main ...

New modular fixed point neutrino models and their phenomenological implications for JUNO, T2HK and DUNE

Journal of High Energy Physics
We perform a general analysis of minimal modular fixed point models based on two right-handed neutrinos (2RHNs) and three modular fixed points for minimal Kähler potential, and find that the only viable possibilities are based on modular S 4 ′ $$ {S}_4^{\

Evaluation of Digital Technologies for Home‐Based Assessment in People With Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Digital technologies hold promise for transforming healthcare by enhancing personalized treatments and offer valuable opportunities to improve patient care. Here, we evaluated several novel, self‐administered, home‐based, digital endpoints for their association with corresponding conventional standard clinical measures (primary) in ...

A 4 modular flavour model of quark mass hierarchies close to the fixed point τ = i∞

Journal of High Energy Physics, 2023
We study the possibility to generate the quark mass hierarchies as well as the CKM quark mixing and CP violation without fine-tuning in a quark flavour model with modular A 4 symmetry.

New Onset of Fibromyalgia After Exposure to a Combat Environment: A Longitudinal Cohort Study

Arthritis Care &Research, EarlyView.
Objective Traumatic life events are hypothesized to be triggers for the onset of fibromyalgia. Posttraumatic stress disorder (PTSD) is a common comorbidity of fibromyalgia. However, limited prospective data are available on the development of fibromyalgia after exposure to high‐magnitude stress.

Predictions from a U(2) flavour symmetry in supersymmetric theories [PDF]

, 1995
In a generic supersymmetric extension of the Standard Model, whether unified or not, a simple and well motivated U(2) symmetry, acting on the lightest two generations, completely solves the flavour changing problem and necessarily leads to a predictive ...

Modular flavor symmetries and fermion mass hierarchies

Journal of High Energy Physics
We investigate fermion mass hierarchies in models with modular flavor symmetries. Several key conclusions arise from the observation that the determinants of mass matrices transform as 1-dimensional vector-valued modular forms. We demonstrate that, under

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.

Leading logarithms in N-flavour mesonic Chiral Perturbation Theory [PDF]

Nuclear Physics B, 2013
We extend earlier work on leading logarithms in the massive nonlinear O(n) sigma model to the case of SU(N)xSU(N)/SU(N) which coincides with mesonic chiral perturbation theory for N flavours of light quarks. We discuss the leading logarithms for the mass and decay constant to six loops and for the vacuum expectation value to seven loops.
