Study of ZZ production in $e^{+}e^{-}$ collisions at $\sqrt{s}$ = 189 GeV with the L3 detector at LEP
A study of ZZ production using the 176 pb/sup -1/ of integrated luminosity collected by the L3 detector at LEP at the center of mass energy of 188.66 GeV is performed. The ZZ production cross section is measured to be sigma /sub ZZ/=0.54/sub -0.14//sup +0.16/ pb, in agreement with the Standard Model...
