Description
We perform a quantitative study of different methods used to solve evolution equations in QCD ($\alpha_s$, PDFs, TMDs).
We highlight differences and similarities between numerical and analytical solutions, focusing on the $q_T$ spectrum of Drell-Yan pair production analysed in the context of TMD/SCET-factorisation vs. qT-resummation formalism.
The final aim is to provide a reliable theoretical-uncertainty estimate that will eventually allow for a faithful determination of non-perturbative effects from fits to data.
