Minimal Flavor Violation

TL;DR

This paper discusses the principle of Minimal Flavor Violation as a necessary framework for new physics models addressing fine-tuning issues, reviewing its extensions to leptons and grand unified theories.

Contribution

It provides a comprehensive review of the principle of Minimal Flavor Violation and explores recent extensions to leptons and GUTs, emphasizing its importance in new physics.

Findings

Minimal Flavor Violation is essential for new physics addressing hierarchy problems.

Extensions to lepton sectors and GUTs have been developed.

The principle helps constrain flavor-changing processes in beyond Standard Model theories.

Abstract

If new physics is called upon to explain away fine tunings, like the hierarchy problem, then, we argue, the principle of Minimal Flavor Violation is inescapable. We review the principle and recent extensions to the lepton sector and to Grand-Unified theories.
