Physics

Scientific paper

The status of the first measurement by ATLAS of Standard Model ZZ production decaying to two leptons and two neutrinos will be presented. Using LHC data at √s = 7 TeV taken during 2011, the expected significance of this signal is nearly 5σ. The intent is to measure the cross section of this process and to put limits on anomalous triple gauge couplings. This channel is an important background to Higgs searches with a heavy Higgs boson decaying to two Z bosons. It is also an irreducible background to associated production of a Higgs boson with a Z boson where the Higgs decays to invisible particles.
