Decoupling of the $\epsilon$-scalar mass in softly broken supersymmetry

Abstract

It has been shown recently that the introduction of an unphysical ϵ\epsilon-scalar mass m~\tilde{m} is necessary for the proper renormalization of softly broken supersymmetric theories by dimensional reduction (\drbar\drbar). In these theories, both the two-loop β\beta-functions of the scalar masses and their one-loop finite corrections depend on m~2\tilde{m}^2. We find, however, that the dependence on m~2\tilde{m}^2 can be completely removed by slightly modifying the \drbar renormalization scheme. We also show that previous \drbar calculations of one-loop corrections in supersymmetry which ignored the m~2\tilde{m}^2 contribution correspond to using this modified scheme.
