Abstract
The study of vector boson scattering (VBS) and vector boson fusion (VBF) processes is crucial for testing the Standard Model (SM). This report focuses on two analyses: the electroweak production of opposite-sign W±W∓ bosons in the fully leptonic decay channel and the electroweak WV production in the semileptonic decay channel. Additionally, it briefly covers the ongoing single W boson electroweak production analysis. The data sample analyzed corresponds to an integrated luminosity of 138 fb−1 of proton-proton collisions at √s = 13 TeV collected by the CMS detector. The VBS W±W∓ signal is observed with a significance of 5.6 standard deviations (5.2 expected) and a measured fiducial cross-section of 10.2±2.0 fb, consistent with the SM prediction of 9.1 ± 0.6 fb. The VBS WV process shows the first evidence with a significance of 4.4 standard deviations observed (5.1 expected) and a measured fiducial cross-section of 1.9±0.5 fb, matching the SM prediction of 2.2 ±0.1 fb. Finally, the VBF W analysis is expected to have a 15% uncertainty on the fiducial cross-section measurement.
