Abstract

Renormalization schemes for tan(beta) are discussed in view of their gauge dependence. It is shown that several common renormalization schemes lead to a gauge-dependent definition of tan(beta), whereas two classes of gauge-independent schemes show even worse disadvantages. We conclude that the DRbar-scheme is the best compromise.
