ZZ Cross Section Measurements
Salvatore Mele (CERN, On behalf of the four LEP Collaborations)
TL;DR
This paper reports measurements of Z boson pair-production cross sections at LEP, including neutral-current four-fermion production and b-quark enriched ZZ events, all aligning with Standard Model predictions.
Contribution
It provides new experimental cross section measurements for Z boson pairs and related processes at LEP, confirming Standard Model predictions.
Findings
Measured cross sections agree with Standard Model
Neutral-current four-fermion production results included
ZZ events with b quarks analyzed
Abstract
Results on the cross section measurement of Z boson pair-production at LEP are presented. The more general case of neutral-current four-fermion production and the particular case of ZZ events enriched in b quarks are also discussed. All the results agree with the Standard Model predictions.
