Field-theoretic Methods in Strongly-Coupled Models of General Gauge Mediation

Understand

An often-exploited feature of the operator product expansion (OPE) is that it incorporates a splitting of ultraviolet and infrared physics.

• In this paper we use this feature of the OPE to perform simple, approximate computations of soft masses in gauge-mediated supersymmetry breaking.
• The approximation amounts to truncating the OPEs for hidden-sector current-current operator products.
• Our method yields visible-sector superpartner spectra in terms of vacuum expectation values of a few hidden-sector IR elementary fields.
