First observation of WZ production and search for ZZ at CDF

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Using L dt = 1.1 fb-1 of data, we searched for WZ and ZZ production. We observe 16 WZ → leptons + ET candidates with an expected background of 2.70 ± 0.28 (stat.) ± 0.34 (syst.) → First observation (5.9σ) of WZ production! Our measured cross section is: σ(WZ)=5.0-1.6 +1.8 (stat.+syst.) pb We observe 1 ZZ μ+μ-μ+μ- candidate with an expected background of 0.009 ± 0.007 (stat.) ± 0.004 (syst.) and ZZ signal of 1.884 ± 0.015 (stat.) ± 0.128 (syst.) We set the following limit: σ(ZZ)<3.8 pb (95% C.L.).
