Abstract

CERN-LHC. A search for resonant WZ production in the l nu lprime lprime (l, lprime = e,mu) decay channel using 20.3 fb^-1 of sqrt(s) = 8 TeV pp collision data collected by the ATLAS experiment at LHC is presented. No significant deviation from the Standard Model prediction is observed and upper limits on the production cross sections of WZ resonances from an extended gauge model W^prime and from a simplified model of heavy vector triplets are derived. A corresponding observed (expected) lower mass limit of 1.52 (1.49) TeV is derived for the W^prime at the 95% confidence level. UPDATE (05 NOV 2014): corrections to Data column in Tables 3,43,44,45,46.
