Vector boson plus jets measurements at ATLAS, CMS, and LHCb

The study of vector boson production in association with jets (V+jets, where V = $W$, $Z$, $\gamma$) is a crucial component of the LHC physics program. These processes serve both as stringent tests of perturbative Quantum Chromodynamics (pQCD) and as important backgrounds in searches for new physics and precision measurements, including Higgs boson studies and top quark analyses. Precise modeling and measurement of V+jets final states provide valuable constraints on theoretical predictions and Monte Carlo (MC) event generators, especially in regions of high jet multiplicity or large transverse momentum. In this contribution recent V + jets measurements by the ATLAS, CMS and LHCb experiments are reviewd. These includes, the evidence of longitudinally polarised $W$ bosons, the measurement of EW $\gamma$ + jets production, cross section measurements for the production of of a W boson + high $p_T$ jets and the search for rare decays $Z \to D^0 \gamma$ and $W^+ \to D_s^+ \gamma$.

Abstract

The study of vector boson production in association with jets (V+jets, where V = $W$, $Z$, $\gamma$) is a crucial component of the LHC physics program. These processes serve both as stringent tests of perturbative Quantum Chromodynamics (pQCD) and as important backgrounds in searches for new physics and precision measurements, including Higgs boson studies and top quark analyses. Precise modeling and measurement of V+jets final states provide valuable constraints on theoretical predictions and Monte Carlo (MC) event generators, especially in regions of high jet multiplicity or large transverse momentum. In this contribution recent V + jets measurements by the ATLAS, CMS and LHCb experiments are reviewd. These includes, the evidence of longitudinally polarised $W$ bosons, the measurement of EW $\gamma$ + jets production, cross section measurements for the production of of a W boson + high $p_T$ jets and the search for rare decays $Z \to D^0 \gamma$ and $W^+ \to D_s^+ \gamma$.
