SUMMARY:A Measurement of ZZ Production with the ATLAS Detector - Steven Ka
 neti (Cambridge)
DTSTART:20140304T150000Z

CONTACT:Susan Haines
DESCRIPTION:The production of gauge boson (W\, Z\, gamma) pairs provides a
  rich set of processes with which the Standard Model can be tested. Diboso
 n processes are background for many processes predicted by many BSM models
 \, making precise knowledge of their production cross sections very import
 ant for discovering new physics.  Dibosons also serve as a good way for lo
 oking for new physics in a more general and model independent fashion via 
 anomalous triple gauge couplings (aTGCs).  This talk will focus on the pro
 duction of pairs of Z bosons\, and analysis via the decay channels ZZ->llv
 v\, and ZZ->lll'l'.  I will discuss the analysis in detail\, describing ev
 ent selection\, background estimates and parameter extraction techniques l
 eading up to a measurement of the ZZ cross section 7 TeV with 4.6 fb-1 of 
 data with the ATLAS detector.  I will also present unfolded\nspectra and l
 imits on anomalous triple gauge coupling parameters.  The status of the ZZ
  analysis at 8  TeV with 20.3 fb-1 will also be summarized.  The talk will
  conclude with an overview of ATLAS electroweak results.
