Massive Ghosts in Softly Broken SUSY Gauge Theories
Abstract
It is shown that, due to soft supersymmetry breaking in gauge theories within the superfield formalism, there appears the mass for auxiliary gauge fields. It enters into the RG equations for soft masses of physical scalar particles and can be eliminated by solving its own RG equation. Explicit solutions up to the three-loop order in the general case and in the MSSM are given. The arbitrariness in choosing the initial condition is discussed.
