Solving the strong CP problem without axions

Journal of High Energy Physics
We formulate general conditions under which the strong CP problem is solved by spontaneous CP violation. Quark-mass matrix elements are polynomials in the CP-breaking order parameters, engineered such that their determinant is a real constant.

Universal predictions of Siegel modular invariant theories near the fixed points

Journal of High Energy Physics
We analyze a general class of locally supersymmetric, CP and modular invariant models of lepton masses depending on two complex moduli taking values in the vicinity of a fixed point, where the theory enjoys a residual symmetry under a finite group.

Modular flavor models with positive modular weights: a new lepton model building

Journal of High Energy Physics
We propose an interesting assignment of positive modular weights for fields in a modular non-Abelian discrete flavor symmetry. By this assignment, we can construct inverse seesaw and linear seesaw models without any additional symmetries which possess ...

The flavour puzzle and flavour symmetries

, 2017
The presence of approximate flavour symmetries is invoked to make New Physics models near the TeV scale compatible with the very demanding quark flavour violation tests. These tests pose a serious threat for any acceptable Standard Model extension at the TeV scale, motivated by naturalness issues.

New physics in the third generation. A comprehensive SMEFT analysis and future prospects

Journal of High Energy Physics
We present a comprehensive analysis of electroweak, flavor, and collider bounds on the complete set of dimension-six SMEFT operators in the U(2)5-symmetric limit. This operator basis provides a consistent framework to describe a wide class of new physics

Flavour Permutation Symmetry and Fermion Mixing

, 2008
We discuss our recently proposed S3(down)xS3(up) flavour-permutation-symmetric mixing observables, giving expressions for them in terms of (moduli-squared) of the mixing matrix elements. We outline their successful use in providing flavour-symmetric descriptions of (non-flavour-symmetric) lepton mixing schemes.
