Generalized transverse momentum distributions, one of the most fundamental hadronic quantities, share the same problematic issue as the transverse momentum distributions: rapidity divergences.
In order to cancel them, a (square root of a) soft function should also be included in their definition.
By doing this, we manage to obtain their evolution kernel, which is universal for all polarizations.
