Self-contained definition of the Collins-Soper kernel

24 Oct 2020 Vladimirov Alexey A.

The rapidity anomalous dimension (RAD), or Collins-Soper kernel, defines the scaling properties of transverse momentum dependent distributions and can be extracted from the experimental data. I derive a self-contained nonperturbative definition that represents RAD without reference to a particular process... (read more)
