Supersymmetric Flavor-Changing Sum Rules as a Tool for b -> s gamma

TL;DR

This paper derives sum rules linking squark masses and flavor-violating mixings in SUSY, aiding the interpretation of indirect b -> s gamma measurements to identify supersymmetric contributions.

Contribution

It introduces new sum rules for minimally flavor-violating SUSY theories at various tan(beta) values, connecting collider and flavor physics data.

Findings

Sum rules relate squark masses to flavor-violating mixings.

Gluino contributions to b -> s gamma are significant at large tan(beta).

Sum rules can help disentangle different SUSY effects.

Abstract

The search for supersymmetry (SUSY) and other classes of new physics will be tackled on two fronts, with high energy, direct detection machines, and in high precision experiments searching for indirect signatures. While each of these methods has its own strengths, even more can be gained by finding ways to combine their results. In this paper, we examine one way of bridging these two types of experiments by calculating sum rules which link physical squark masses to the flavor-violating squark mixings. These sum rules are calculated for minimally flavor-violating SUSY theories at both high and low tan(beta). We also explore how the sum rules could help to disentangle the relative strengths of different SUSY contributions to b -> s gamma, a favored channel for indirect searches of new physics. Along the way, we show that the gluino contributions to b -> s gamma can be very sizable at large tan(beta).
