Production of Z-bosons in the parton branching method / Bermudez Martinez, A. (DESY) ; Connor, P. (DESY) ; Dominguez Damiani, D. (DESY) ; Estevez Banos, L.I. (DESY) ; Hautmann, F. (Antwerp U. ; Basque U., Bilbao ; CERN) ; Jung, H. (DESY) ; Lidrych, J. (DESY) ; Schmitz, M. (DESY) ; Taheri Monfared, S. (DESY) ; Wang, Q. (DESY ; Peking U.) et al.
Transverse Momentum Dependent (TMD) parton distributions obtained from the Parton Branching (PB) method are combined with next-to-leading-order (NLO) calculations of Drell-Yan (DY) production. We apply the MCatNLO method for the hard process calculation and matching with the PB TMDs. [...]

The small $k_{\textrm{T}}$region in Drell–Yan production at next-to-leading order with the parton branching method / Bubanja, I. (Montenegro U. ; Vrije U., Brussels) ; Bermudez Martinez, A. (CERN) ; Favart, L. (Vrije U., Brussels) ; Guzman, F. (Unlisted, CU) ; Hautmann, F. (CERN ; Antwerp U. ; Oxford U.) ; Jung, H. (DESY ; Hamburg U., Inst. Theor. Phys. II) ; Lelek, A. (Antwerp U.) ; Mendizabal, M. (DESY) ; Figueroa, K. Moral (DESY) ; Moureaux, L. (Hamburg U.) et al.
The Parton Branching (PB) method describes the evolution of transverse momentum dependent (TMD) parton distributions, covering all kinematic regions from small to large transverse momenta kT. The small kT-region is very sensitive both to the contribution of the intrinsic motion of partons (intrinsic kT) and to the resummation of soft gluons taken into account by the PB TMD evolution equations.

Extending parton branching TMDs to small $x$ / Monfared, Sara Taheri (DESY) ; Hautmann, Francesco (Oxford U. ; Basque U., Bilbao ; Antwerp U. ; Rutherford ; Oxford U., Theor. Phys.) ; Jung, Hannes (DESY) ; Schmitz, Melanie (DESY)
We explore the possibility to include small-$x$ dynamics effects in the parton branching (PB) approach to transverse momentum dependent (TMD) parton distribution functions. To this end, we first revisit the PB method at leading order, presenting a new fit to inclusive-DIS precision data, and performing a numerical study of the dynamic soft-gluon resolution scale. [...]

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..

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. [...]

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.

Azimuthal correlations in high pT processes with the TMD parton branching method at NLO / van Kampen, Mees (Antwerp U.) ; Martinez, A Bermudez (DESY) ; Banos, L I Estevez (DESY) ; Hautmann, F (Antwerp U. ; CERN ; Oxford U.) ; Jung, H (DESY) ; Mendizabal, M (DESY) ; Figueroa, K Moral (Edinburgh U.) ; Prestel, S (Lund U.) ; Monfared, S Taheri (DESY) ; Wang, Q (DESY ; Peking U.) et al.
We discuss our recent results on azimuthal distributions in vector boson + jets and multi-jet production at the LHC, obtained from the matching of next-to-leading order (NLO) perturbative matrix elements with transverse momentum dependent (TMD) parton branching. We present a comparative analysis of boson-jet and jet-jet correlations in the back to-back region, and a study of the theoretical systematic uncertainties associated with the matching scale in the cases of TMD and collinear parton showers..

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.
