$Z Z o ell^_s16 ell^-$ v anti-v production in $p arp$ collisions at $sqrts$ = 1.96-TeV

Abstract

We describe a search for Z boson pair production in pp collisions at sqrt(s)= 1.96 TeV with the D0 detector at the Fermilab Tevatron Collider using a data sample corresponding to an integrated luminosity of 2.7 fb^-1. Using the final state decay ZZ to llvv (where l = e or mu) we measure a signal with a 2.6 standard deviations significance (2.0 expected) and measure a cross section of sigma(pp to ZZ _s16 X) = 2.01 _s16- 0.93 (stat.) _s16- 0.29 (sys.) pb.
