      abstract     = {Collinear and transverse momentum dependent (TMD) parton
                      densities are obtained from fits to precision measurements
                      of deep inelastic scattering (DIS) cross sections at HERA.
                      The parton densities are evolved by DGLAP evolution with
                      next-to-leading-order (NLO) splitting functions using the
                      parton branching method, allowing one to determine
                      simultaneously collinear and TMD densities for all flavors
                      over a wide range in $x$, $\mu^2$ and $k_t$, relevant for
                      predictions at the LHC. The DIS cross section is computed
                      from the parton densities using perturbative NLO coefficient
                      functions. Parton densities satisfying angular ordering
                      conditions are presented. Two sets of parton densities are
                      obtained, differing in the renormalization scale choice for
                      the argument in the strong coupling $\alpha_s$. This is
                      taken to be either the evolution scale $\mu$ or the
                      transverse momentum $q_t$. While both choices yield
                      similarly good $\chi^2$ values for the fit to DIS
                      measurements, especially the gluon density turns out to
                      differ between the two sets. The TMD densities are used to
                      predict the transverse momentum spectrum of $Z$-bosons at
                      the LHC.},
