Development of a multivariate analysis for the study of the production of a W boson in association with 2 b-jets with the ATLAS experiment at the LHC

Year: 2025

Type: article

Abstract: This study investigates the production of a W boson in association with two b-jets in proton-proton collisions using the ATLAS detector at the LHC. A Neural Network approach is optimized to suppress the huge top-quark background, marking a step toward the first differential cross-section measurement of this process. The analysis is based on Monte Carlo simulations emulating the dataset collected by the ATLAS experiment at √s = 13 TeV. The study assumes an integrated luminosity of 140 fb−1, corresponding to the full Run-2 dataset.
