Flavor structure from `canonical' Yukawa interactions and `emergent' kinetic terms

TL;DR

This paper explores how the flavor structure of quarks in the Standard Model can arise from canonical Yukawa interactions and the emergence of kinetic terms through radiative corrections involving massive states.

Contribution

It proposes a novel mechanism where quark kinetic terms emerge in the infrared, shaping the flavor structure via radiative corrections from heavy states.

Findings

Realistic quark flavor structures can be generated through this emergence process.

Kinetic terms appear in the IR region due to radiative corrections involving towers of massive states.

The framework offers a new perspective on flavor generation in the Standard Model.

Abstract

We study the flavor structure of quarks in the standard model from a viewpoint of a canonical type of Yukawa interactions and an emergence of kinetic terms. A realistic structure can be generated based on the emergence proposal that quark kinetic terms appear in the infra-red region, as a result of radiative corrections involving towers of massive states.
