Jan Ferdyan (UJ): Probing gluon TMD models with Drell-Yan structure functions

→ Europe/Warsaw
Description

Abstract:

We study the Drell-Yan structure functions within the $k_T$-factorization framework, with particular emphasis on the Lam-Tung relation. We consider two scattering channels at the tree level, dominated by gluon contributions (two off-shell gluons scattering and valence quark - off-shell gluon scattering). Within this approach, we probe various gluon transverse momentum distribution (TMD) models and compare the results with the ATLAS data. We observe that the Drell-Yan structure functions distinguish between the chosen TMD models, and in particular, that a reasonably good description of the Lam-Tung relation can be achieved within this formalism for some of the considered TMD models.
