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..

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..

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..

TMD Evolution and Multi-Jet Merging / Bermudez Martinez, A. (DESY) ; Hautmann, F. (U. Antwerp (main) ; Oxford U.) ; Mangano, M.L. (CERN)
The theoretical description of the physics of multi-jets in hadronic collisions at high energies is based on "merging" methods, which combine short-timescale production of jets with long-timescale evolution of partonic showers. We point out potential implications of the evolution of transverse momentum dependent (TMD) distributions on the structure of multi-jet states at high energies, and in particular on the theoretical systematics associated with multi-jet merging.

Multi-jet merging with TMD parton branching / Bermudez Martinez, A. (DESY) ; Hautmann, F. (CERN ; Antwerp U. ; Rutherford ; U. Oxford (main)) ; Mangano, M.L. (CERN)
One of the main theoretical systematics in studies of final states with large jet multiplicities at high-energy hadron colliders is associated with the merging of QCD parton showers and hard-scattering matrix elements. We present a method to incorporate the physics of transverse momentum recoils due to initial-state shower evolution into multi-jet merging algorithms by using the concept of transverse momentum dependent (TMD) distributions and the associated parton branching.

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. [...]

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.

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. [...]
