The Parton Branching Sudakov and its relation to CSS / Martinez, A Bermudez (CERN) ; Hautmann, F (CERN ; Antwerp U. ; Oxford U.) ; Keersmaekers, L (Antwerp U.) ; Lelek, A (Antwerp U.) ; Mendizabal Morentin, M (DESY, Zeuthen) ; Monfared, S Taheri (DESY, Zeuthen) ; van Kampen, A M (Antwerp U.)
The Transverse Momentum Dependent (TMD) Parton Branching (PB) method is a Monte Carlo (MC) approach to obtain QCD high energy collider predictions grounded in ideas originating from the TMD factorization. It provides an evolution equation for the TMD parton distribution functions (TMDs) and a framework to use those within TMD MC generators.This work focuses on the structure of the PB Sudakov form factor.

Merging scale in Z + multi-jet events for varying masses / van Kampen, Aron Mees (Antwerp U.) ; Hautmann, Francesco (Antwerp U. ; Oxford U.) ; Martinez, Armando Bermudez (CERN)
We investigate theoretical predictions for $Z$-boson plus jets production using multi-jet merging algorithms. By studying the differential jet rates and their discontinuities, we develop a method to quantitatively analyze the merging algorithm and merging scale dependence on varying boson's invariant masses..

Back-to-back azimuthal correlations in $\mathrm {Z} +$jet events at high transverse momentum in the TMD parton branching method at next-to-leading order / Yang, H. (Peking U. ; DESY) ; Bermudez Martinez, A. (DESY) ; Banos, L.I. Estevez (DESY) ; Hautmann, F. (CERN ; Antwerp U. ; Oxford U.) ; Jung, H. (DESY) ; Mendizabal, M. (DESY) ; Figueroa, K. Moral (Edinburgh U.) ; Prestel, S. (Lund U., Dept. Theor. Phys.) ; Monfared, S. Taheri (DESY) ; van Kampen, A.M. (Antwerp U.) et al.
Azimuthal correlations in 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. [...]

Drell-Yan transverse spectra at the LHC: a comparison of parton branching and analytical resummation approaches / van Kampen, Aron Mees (Antwerp U.)
I report on precision comparisons of theoretical predictions for Drell-Yan (DY) transverse momentum spectra from two approaches: the analytical resummation approach based on Collins-Soper-Sterman (CSS) formalism and the parton branching (PB) approach to the evolution of transverse momentum dependent (TMD) parton distributions..

Dynamical resolution scale in transverse momentum distributions at the LHC / Hautmann, F. (Antwerp U. ; Oxford U. ; CERN ; Basque U., Bilbao) ; Keersmaekers, L. (Antwerp U.) ; Lelek, A. (Antwerp U.) ; Van Kampen, A.M. (Antwerp U.)
The QCD evolution of transverse momentum dependent (TMD) distribution functions has recently been formulated in a parton branching (PB) formalism. In this approach, soft-gluon coherence effects are taken into account by introducing the soft-gluon resolution scale and exploiting the relation between transverse-momentum recoils and branching scales.
