Description
The non-perturbative partof the TMDs has been the object of many phenomenologucal studies.
We consider here a renormalon analysis of TMDs which provides the leading corrections to the perturbative estimations of TMDs. We can identify two sources of renormalons which should be taken into account separately.
We also show that theTMDs have a non-trivial dependence on Bjorken variables. All these information can be used to provide consistent models/ansätze for TMD phenomenology.
