Transverse-momentum dependent Distributions: Functional Complexity manifesting in Gluon Poles and Inverse Radon Transforms


As well-known, QCD can be applied to the description of hard reactions with the help of the factorization theorem.
The factorization theorem, as an extended method of asymptotical estimations, states that the short (hard) and long (soft) distance dynamics can be separated out provided the momentum transfer is large. In this connection, any types of parton distributions are stemming from the factorization procedure applied for a given hard process. In the talk, we discuss the functional complexity which is associated with the transverse momentum dependent parton distributions. Working with the semi-exclusive and inclusive reactions, we demonstrate the manifestation of complexity in the gluon pole contributions and in the inverse Radon transforms applied to the transverse momentum dependent generalized
parton distributions. The experimental observables which are directly probing the gluon poles have been suggested.
