Soft supersymmetry breaking terms from D4 x Z2 lepton flavor symmetry

TL;DR

This paper investigates how a specific $D_4 imes Z_2$ lepton flavor symmetry influences soft supersymmetry breaking terms, analyzing their structure and experimental constraints in a supersymmetric model.

Contribution

It provides a detailed evaluation of soft supersymmetry breaking terms predicted by the $D_4$ flavor model and examines experimental flavor-changing neutral current constraints.

Findings

Soft slepton masses are constrained by flavor experiments.

A-terms exhibit specific patterns due to $D_4$ symmetry.

Model predictions are consistent with current experimental bounds.

Abstract

We study the supersymmetric model with $D_4 \times Z_2$ lepton flavor symmetry. We evaluate soft supersymmetry breaking terms, i.e. soft slepton masses and A-terms, which are predicted in the $D_4$ flavor model. We consider constraints due to experiments of flavor changing neutral current processes.
