Title: Disentangling soft and collinear effects in QCD parton showers

Abstract

We introduce a method for the separation of soft and collinear logarithms in QCD parton evolution at $O (α_{s}^{2})$ and at leading color. Using an implementation of the technique in the dire parton shower, we analyze the numerical impact of genuine triple-collinear corrections from quark pair emission in $e^{+} e^{-} \to$ hadrons.
