A CP-safe solution of the mu/ Bmu problem of gauge mediation

TL;DR

This paper presents a model in gauge mediation that naturally generates mu and B parameters of similar scale without large CP violation, achieved through independent mass scale determination and phase alignment via supergravity coupling.

Contribution

It introduces a novel gauge mediation model where mu and B are generated independently with aligned phases, avoiding CP violation issues.

Findings

Mu and B are of the same order without large CP phases

Phase alignment occurs dynamically through supergravity coupling

Model demonstrates independent control of mass scales

Abstract

We construct a model that naturally generates mu and B of the same order without producing large CP violating phases. This is easily accomplished once one permits these mass scales to be determined independently of the ordinary gauge-mediated soft masses. The alignment of phases is shown to emerge dynamically upon coupling to supergravity and is not unique to the model presented here.
