Twistor Strings with Flavour [PDF]

, 2007
We explore the tree-level description of a class of N=2 UV-finite SYM theories with fundamental flavour within a topological B-model twistor string framework.

Gauge Theories in a Bag [PDF]

, 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 $\theta$.

Modular binary octahedral symmetry for flavor structure of Standard Model

Journal 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

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

Journal 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

Journal 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.

Maximal Sfermion Flavor Violation in Super-GUTs [PDF]

, 2016
We consider supersymmetric grand unified theories with soft supersymmetry-breaking scalar masses $m_0$ specified above the GUT scale (super-GUTs) and patterns of Yukawa couplings motivated by upper limits on flavour-changing interactions beyond the ...

SPONTANEOUS CP IN A SUSY THEORY OF FLAVOUR

String 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]

Progress 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?

Journal 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 ...
