TMD densities from the Parton branching method

Radek Zlebcik

Abstract

We present results from a Parton branching solution of the DGLAP equation at LO, NLO and NNLO which is is capable to extract both the collinear part and the transverse momentum de- pendent part of the parton densities. We demonstrate that within our method the collinear part of parton densities exactly corresponds to the semi-analytical solution of the DGLAP equation up to NNLO. Moreover, we study the transverse momentum of parton densities with respect to the parton flavour, ordering condition used during the evolution and the intrinsic momentum.
