      abstract     = {Azimuthal correlations in $\mathrm {Z} +$jet production at
                      large transverse momenta are computed by matching
                      Parton-Branching (PB) TMD parton distributions and showers
                      with NLO calculations via MCatNLO. The predictions are
                      compared with those for dijet production in the same
                      kinematic range. The azimuthal correlations $\Delta \phi $
                      between the Z boson and the leading jet are steeper compared
                      to those in dijet production at transverse momenta
                      $\mathcal{O}(100)$ GeV , while they become similar for very
                      high transverse momenta ${{\mathcal {O}}}(1000)$ GeV . The
                      different patterns of $\mathrm {Z} +$jet and dijet azimuthal
                      correlations can be used to search for potential
                      factorization-breaking effects in the back-to-back region,
                      which depend on the different color and spin structure of
                      the final states and their interferences with the initial
                      states. In order to investigate these effects
                      experimentally, we propose to measure the ratio of the
                      distributions in $\Delta \phi $ for $\mathrm {Z} +$jet- and
                      multijet production at low and at high transverse momenta,
                      and compare the results to predictions obtained assuming
                      factorization. We examine the role of theoretical
                      uncertainties by performing variations of the factorization
                      scale, renormalization scale and matching scale. In
                      particular, we present a comparative study of matching scale
                      uncertainties in the cases of PB-TMD and collinear parton
                      showers.},
