Wrinkles in the Froggatt-Nielsen mechanism and flavorful new physics

open access: yesJournal 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.

Modular binary octahedral symmetry for flavor structure of Standard Model

open access: yesJournal of High Energy Physics, 2023
We have investigated the modular binary octahedral group 2O as a flavor symmetry to explain the structure of Standard Model. The vector-valued modular forms in all irreducible representations of this group are constructed. We have classified all possible

Quarks at the modular S 4 cusp

open access: yesJournal of High Energy Physics, 2023
We analyse the possibility of describing quark masses, mixing and CP violation in S 4 ′ $$ {S}_4^{\prime } $$ modular flavour models without flavons. We focus on the case where the closeness of the modulus to the point of residual ℤ 3 ST $$ {\mathbb{Z ...

SPONTANEOUS CP IN A SUSY THEORY OF FLAVOUR

open access: yesString Phenomenology 2003, 2004
We present a model based on an SU(3) family symmetry providing a full description of quark and lepton masses and mixing angles. CP is spontaneously broken in the flavour sector reproducing the observed results of the Jarlskog invariant in the CKM mixing matrix.

Possible Origin of Flavour Mixings in the Horizontal Gauge Theory [PDF]

open access: yesProgress of Theoretical Physics, 1993
It is shown that the horizontal gauge interactions with a certain type of broken gauge symmetries lead us to the non-trivial flavour mixings involving the CP violation effect. One finds out that both the radiative corrections due to the vertical gauge interactions and a non-commutativity of the surviving generators associated with the horizontal gauge ...

Can leptonic mixing matrix have a Wolfenstein form?

open access: yesJournal of High Energy Physics, 2023
We analyze the possibility of the leptonic mixing matrix having a Wolfenstein form at the Grand Unified Theory scale. The renormalization group evolution of masses and mixing angles from the high scale to electroweak scale, in certain new physics ...

Fermion hierarchies in SU(5) grand unification from Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry

open access: yesJournal of High Energy Physics, 2023
We construct an SU(5) grand unified model in which the hierarchies of the quark and lepton masses and mixing are explained by the Γ 6 ′ $$ {\Gamma}_6^{\prime } $$ modular flavor symmetry.

CKM substructure from the weak to the Planck scale

open access: yesJournal of High Energy Physics, 2022
We look for relations among CKM matrix elements that are not consequences of the Wolfenstein parametrization. In particular, we search for products of CKM elements raised to integer powers that approximately equal 1.
