CSIC ORCID | Fecha de publicación: | 2019 | Editor: | Elsevier | Citación: | Physics Letters B 789: 19-44 (2019) | Resumen: | This Letter reports measurements of differential cross sections for the production of two Z bosons in association with jets in proton–proton collisions at √s = 8 and 13 TeV. The analysis is based on data samples collected at the LHC with the CMS detector, corresponding to integrated luminosities of 19.7 and 35.9fb-1 at 8 and 13 TeV, respectively. The measurements are performed in the leptonic decay modes ZZ→ℓℓℓℓ, where ℓ,ℓ=e,μ. The differential cross sections as a function of the jet multiplicity, the transverse momentum p, and pseudorapidity of the p -leading and subleading jets are presented. In addition, the differential cross sections as a function of variables sensitive to the vector boson scattering, such as the invariant mass of the two p -leading jets and their pseudorapidity separation, are reported. The results are compared to theoretical predictions and found in good agreement within the theoretical and experimental uncertainties. | Descripción: | The CMS Collaboration: et al. | Versión del editor: | https://doi.org/10.1016/j.physletb.2018.11.007 | URI: | http://hdl.handle.net/10261/213313 | DOI: | 10.1016/j.physletb.2018.11.007 | Identificadores: | doi: 10.1016/j.physletb.2018.11.007 issn: 0370-2693 issn: 1873-2445 |
