In this talk I will briefly address the state of the art for our understanding of transverse-momentum-dependent distributions. I will also introduce some of the topics which are currently under investigation and highlight the fundamental role of the present experimental facilities for the advancement of the field.
TMDs match collinear PDFs in the limit of small transverse distances. We study the bias on the TMD extraction caused by the choice of the PDF set. The bias is reduced by introducing a flavour dependence on the TMD profile and taking into account the PDF uncertainty. Both points improve the agreement between theory and experiment and should be taken into account in future global analyses.
The azimuthal correlation of high transverse momentum jets in collisions at 13 TeV is studied by applying PB-TMD distributions to NLO calculations via MCatNLO together with the PB-TMD parton shower in Cascade3. A very good description of the cross section as a function of the azimuthal correlation is observed. In the back-to-back region, a very good agreement is observed with the PB-TMD Set 2...
The talk is devoted to the TMD distributions of twist-three and presents their systematic, evolution equations, small-b matching, and other properties. I explicitly demonstrate the non-trivial interplay between T-odd and T-even distributions and the presence of super-leading-power terms.
