Description

The efficiency of non-local subtraction methods such as qT-subtraction or jettiness subtraction is affected by the size of the power corrections below the slicing cutoff used in the calculation. In this talk I will discuss the scaling of the power corrections for different classes of observables, focussing in particular on transverse observables, which do not depend on the rapidity of QCD radiation.
