摘要
We explore the relationship between the DRED and NSVZ renormalization schemes. Using certain exact results for the soft scalar mass beta-function, we derive the transformation of alpha^{DRED} to alpha^{NSVZ} through terms of order alpha^4. We thus incidentally determine beta_alpha^{DRED} through four loops, and we compare our result to a previous Padé Approximant prediction.
