The connection between the DRED and NSVZ renormalisation schemes

摘要

We explore the relationship between the DRED and NSVZ schemes. Using certain exact results for the soft scalar mass beta-function, we derive the transformation of alpha(NSVZ) to alpha(DRED) through terms of order alpha(4). We thus incidentally determine beta(alpha)(DRED) through four loops, and we compare our result to a previous Pade Approximant prediction. (C) 1998 Elsevier Science B.V. All rights reserved.
