Measurement of 𝑊𝑊𝑍 and 𝑍𝐻 Production Cross Sections at $\sqrt{𝑠}$ = 13 and 13.6 TeV
Abstract
A measurement is presented of the cross section in proton-proton collisions for the production of two 𝑊 bosons and one 𝑍 boson. It is based on data recorded by the CMS experiment at the CERN LHC at center-of-mass energies $\sqrt{𝑠}$ = 13 and 13.6 TeV, corresponding to an integrated luminosity of 200 fb −1 . Events with four charged leptons (electrons or muons) in the final state are selected. Both nonresonant 𝑊𝑊𝑍 production and 𝑍𝐻 production, with the Higgs boson decaying into two 𝑊 bosons, are reported. For the first time, the two processes are measured separately in a simultaneous fit. Combining the two modes, signal strengths relative to the standard model (SM) predictions of 0.75$^{+0.34}_{−0.29}$ and 1.74$^{+0.71}_{−0.60}$ are measured for $\sqrt{𝑠}$ = 13 and 13.6 TeV, respectively. The observed (expected) significance for the triboson signal is 3.8 (2.5) standard deviations for $\sqrt{𝑠}$ = 13.6 TeV, thus providing the first evidence for triboson production at this center-of-mass energy. Combining the two modes and the two center-of-mass energies, the inclusive signal strength relative to the SM prediction is measured to be 1.03$^{+0.31}_{−0.28}$, with an observed (expected) significance of 4.5 (5.0) standard deviations.
