Running minimal flavor violation

TL;DR

This paper investigates how the flavor structure in the MSSM behaves under minimal flavor violation, demonstrating that the MFV decomposition remains valid across scales and that coefficients approach fixed points.

Contribution

It shows that imposing MFV at one scale effectively describes flavor effects at all scales through running coefficients and fixed points.

Findings

MFV decomposition remains valid across different energy scales

Coefficients of MFV run to non-trivial fixed points

Quantum effects can be captured by scale-dependent coefficients

Abstract

We consider the flavor structure of the minimal supersymmetric standard model (MSSM) in the framework of `minimal flavor violation' (MFV). We show that, if one imposes the MFV structure at some scale, to a good accuracy the MFV decomposition works at all other scales. That is, quantum effects can be described by running coefficients of the MFV decomposition. We find that the coefficients get driven to non-trivial fixed points.
