Abstract
We obtain the one- and two-loop renormalization group equations for so
ft SUSY-breaking scalar interactions in a general, semisimple SUSY gau
ge model, by using the supergraph method. We find that the method simp
lifies the calculation significantly because of the nonrenormalization
theorem and also because of the property that the relevant divergence
s are derived by simple algebra from those in the exact SUSY case. A d
isagreement with the existing result is found in beta((2))(m(2)) and i
ts cause is briefly discussed.
