Moduli stabilization and light axion by Siegel modular forms
Journal of High Energy PhysicsWe discuss the stabilization of multiple moduli by utilizing Siegel modular forms in the framework of Sp(2g, ℤ) modular invariant theories. For a generic modular- and CP-invariant scalar potential, we find that CP-conserving fixed points are stationary ...

Multiple realizations of modular flavor symmetries and their phenomenology
Journal of High Energy PhysicsWe point out that specifying the finite modular group does not uniquely fix a modular flavor symmetry. We illustrate this using the finite modular group T′. Otherwise equivalent models based on different T′ lead to modular forms with different properties

Deconstructing flavor anomalously
Journal of High Energy PhysicsFlavor deconstruction refers to ultraviolet completions of the Standard Model where the gauge group is split into multiple factors under which fermions transform non-universally.

Flavour hierarchies and $B$-anomalies in a twin Pati-Salam theory of flavour
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 ...

, 2010 We re-examine the one-loop renormalization group equations (RGEs) for the dimensionful parameters of the minimal supersymmetric Standard Model with broken supersymmetry, allowing for arbitrary flavour structure of the soft SUSY breaking (SSB) parameters.

Flavour-mixing gauge field theory of massive Majorana neutrinos
, 2012 A gauge-field theory for massive neutral particles is developed on the basis of the real four-component Majorana equation. By use of its spin operator, a purely imaginary representation of the SU(2) algebra can be defined, which gives a covariant derivative that is real.

Theory of electric dipole moments and lepton flavour violation
, 2016 Electric dipole moments and charged-lepton flavour-violating processes are extremely sensitive probes for new physics, complementary to direct searches as well as flavour-changing processes in the quark sector. Beyond the "smoking-gun" feature of a potential significant measurement, however, it is crucial to understand their implications for new ...

Yukawa hierarchies from spontaneous breaking of the $\bma{SU(3)_L\times SU(3)_R}$ flavour symmetry?
, 2012 The tree level potential for a scalar multiplet of `Yukawa fields' $Y$ for one type of quarks admits the promising vacuum configuration $ \propto {\rm diag}(0,0,1)$ that breaks spontaneously $SU(3)_L\times SU(3)_R$ flavour symmetry.

The global B − L symmetry in the flavor-unified SU(N) theories
Journal of High Energy PhysicsWe study the origin of the global B − L symmetry in a class of flavor-unified theories with gauge groups of SU(N ≥ 6). In particular, we focus on the SU(8) theory which can minimally embed three-generational SM fermions non-trivially.

The Standard Model quark/lepton masses and the Cabibbo-Kobayashi-Maskawa mixing in an SU(8) theory
Journal of High Energy PhysicsThe observed Standard Model (SM) quark/lepton mass hierarchies and the Cabibbo-Kobayashi-Maskawa (CKM) mixing pattern are described in an SU(8) theory through its realistic symmetry breaking pattern with three intermediate stages, which rely on a set of ...
