Search for ZZ and ZH production in the bb¯bb¯ final state using proton-proton collisions at √𝑠 =13TeV
A search for ZZ and ZH production in the bb¯bb¯ final state is presented, where H is the standard model (SM) Higgs boson. The search uses an event sample of proton-proton collisions corresponding to an integrated luminosity of 133fb−1 collected at a center-of-mass energy of 13TeV with the...

| description | A search for ZZ
and ZH
production in the bb¯bb¯
final state is presented, where H is the standard model (SM) Higgs boson. The search uses an event sample of proton-proton collisions corresponding to an integrated luminosity of 133fb−1
collected at a center-of-mass energy of 13TeV
with the CMS detector at the CERN LHC. The analysis introduces several novel techniques for deriving and validating a multi-dimensional background model based on control samples in data. A multiclass multivariate classifier customized for the bb¯bb¯
final state is developed to derive the background model and extract the signal. The data are found to be consistent, within uncertainties, with the SM predictions. The observed (expected) upper limits at 95% confidence level are found to be 3.8 (3.8) and 5.0 (2.9) times the SM prediction for the ZZ
and ZH production cross sections, respectively. |
