Towards the Phenomenology of TMD Distributions at NNLL

Understand

We discuss the recently proposed scheme for the evolution of Transverse Momentum Distributions using the so-called "D^R".

• We discuss a new method to separate perturbative and non-perturbative effects in the analysis of the evolution of Transverse Momentum Distributions.
• We argue that the scheme is compatible with the standard CSS resummation approach when the running of the strong coupling is taken into account properly.
