Comment on ``Success of collinear expansion in the calculation of induced gluon emission''

TL;DR

This paper defends the validity of the collinear expansion method in calculating induced gluon emission against criticisms, asserting that previous objections are either incorrect or irrelevant.

Contribution

It clarifies and counters specific criticisms of the collinear expansion approach in gluon emission calculations, reaffirming its applicability.

Findings

Criticisms against collinear expansion are invalid or irrelevant.

The paper supports the continued use of collinear expansion in relevant calculations.

Reaffirms the correctness of previous results using this method.

Abstract

We show that the arguments against our recent paper on the failure of the collinear expansion in the calculation of the induced gluon emission raised by X.N. Wang are either incorrect or irrelevant.
