Effective Field Theory Analysis on {\mu} Problem in Low-Scale Gauge Mediation

Understand

Supersymmetric models based on the scenario of gague mediation often suffer from the well-known $\mu$ problem.

• In this paper, we reconsider this problem in low-scale gauge mediation in terms of effective field theory analysis.
• In this paradigm, all high energy input soft mass can be expressed via loop expansions.
• If the corrections coming from messenger thresholds are small, as we assume in this letter, then RG evaluations can be taken as linearly approximation for low-scale supersymmetric breaking.
