Renormalization of soft supersymmetry breaking terms by analytic continuation into superspace

Abstract

This paper reviews the renormalization of soft supersymmetry breaking terms using the method of analytic continuation of couplings into superspace. Super-Feynman rules in the softly broken theory are derived. The renormalization group equation for the soft terms in the Wess-Zumino model and the supersymmetric gauge theories are explored and the dimensional reduction scheme is clarified. As applications, the leading results of the gauge-mediated supersymmetry breaking scenario are obtained and the effective potential along the flat direction in the theory containing the flat direction is discussed in this paper.
