Common origin of θ 13 and dark matter within the flavor symmetric scoto-seesaw framework
Journal of High Energy Physics, 2022 To understand the observed pattern of neutrino masses and mixing as well as to account for the dark matter we propose a hybrid scoto-seesaw model based on the A 4 discrete flavor symmetry.

Effective-field theories for charged lepton flavour violation [PDF]
EPJ Web of Conferences, 2018 These proceedings review the status of present and future bounds on muonic lepton flavour violating transitions in the context of an effective-field theory defined below the electroweak scale. A specific focus is set on the phenomenology of μ → eγ, μ → 3e transitions and coherent μ → e nuclear conversion in the light of current and future experiments ...

Accidental SO(10) axion from gauged flavour [PDF]
Journal of High Energy Physics, 2020 An accidental U(1) Peccei-Quinn (PQ) symmetry automatically arises in a class of SO(10) unified theories upon gauging the SU(3)f flavour group. The PQ symmetry is protected by the ℤ4 × ℤ3 center of SO(10) × SU(3)f up to effective operators of canonical ...

Minimally modified Fritzsch texture for quark masses and CKM mixing
Journal of High Energy Physics, 2023 The Standard Model does not constrain the form of the Yukawa matrices and thus the origin of fermion mass hierarchies and mixing pattern remains puzzling.

Aspects of flavour and supersymmetry in F-theory GUTs [PDF]
Journal of High Energy Physics, 2010 We study the constraints of supersymmetry on flavour in recently proposed models of F-theory GUTs. We relate the topologically twisted theory to the canonical presentation of eight-dimensional super Yang-Mills and provide a dictionary between the two.

, 1994 We investigate multi-flavour gauge theories confined in $d\es 2n$-dimensional Euclidean bags. The boundary conditions for the 'quarks' break the axial flavour symmetry and depend on a parameter $\theta$.

Wrinkles in the Froggatt-Nielsen mechanism and flavorful new physics
Journal of High Energy Physics, 2023 When the Froggatt-Nielsen mechanism is used to explain the Standard Model flavor hierarchy, new physics couplings are also determined by the horizontal symmetry.

Flavour hierarchies and $B$-anomalies in a twin Pati-Salam theory of flavour [PDF]
Proceedings of 8th Symposium on Prospects in the Physics of Discrete Symmetries — PoS(DISCRETE2022)In this manuscript, based on arXiv:2209.00276, I present a model which can simultaneously explain and connect the flavour hierarchies of the Standard Model with flavour anomalies in $B$-physics. I will briefly introduce the model and highlight the main features, including a common origin of Yukawa couplings and vector leptoquark $U_{1}$ couplings to ...
