Contribution

It introduces transition rules between regularization schemes and clarifies the scheme dependence in dimensional reduction applications.

Findings

Identifies the origin of regularization-scheme dependence.

Derives transition rules to other schemes.

Discusses collinear singularity structures.

Abstract

We consider the application of regularization by dimensional reduction to NLO corrections of hadronic processes. The general collinear singularity structure is discussed, the origin of the regularization-scheme dependence is identified and transition rules to other regularization schemes are derived.
