Description
TMD observables are sensitive to both perturbative and nonperturbative
QCD effects, in particular in kinematic regions associated with low
transverse momentum. Such observables are described in the CSS formalism
using field theoretic objects like TMD PDFs and TMD FFs which in turn
depend on nonperturbative components. In contrast, MCEG uses parton
shower and hadronization models such as the LUND string in order to
describe the same types of observables. In this talk I will present
ongoing research work that attempts to construct a language dictionary
between the CSS formalism and MCEG with the ultimate goal to develop a
MCEG for TMDs and to improve the TMD formalism.
