A global analysis of the SMEFT under the minimal MFV assumption

Journal of High Energy Physics
We present comprehensive global fits of the SMEFT under the minimal minimal flavour violation (MFV) hypothesis, i.e. assuming that only the flavour-symmetric and CP-invariant operators are relevant at the high scale.

Breaking Standard Model global symmetries with the tau lepton

SciPost Physics Proceedings
Properties of the dynamics of the Standard Model processes such as lepton flavour preservation and lepton, or baryon, number conservation, are usually taken for granted.

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 ...

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.

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
