TL;DR
This paper investigates azimuthal correlations in vector boson + jets and multi-jet production at the LHC, using NLO matrix elements matched with TMD parton branching to understand the underlying QCD dynamics.
Contribution
It introduces a novel analysis of boson-jet and jet-jet azimuthal correlations with a focus on systematic uncertainties from matching scales in TMD and collinear showers.
Findings

Assessment of theoretical uncertainties related to matching scale choices
Insights into the impact of TMD versus collinear parton showers
Abstract
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.
