Sammanfattning

We introduce a method for the separation of soft and collinear logarithms in QCD parton evolution at O(αs2) 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-→ hadrons.
