  A generic search is presented for a heavy particle decaying to WZ to l nu
l'l' (l, l' = e, mu) final states. The data were recorded by the ATLAS detector
in sqrt(s) = 7 TeV pp collisions at the Large Hadron Collider and correspond to
an integrated luminosity of 1.02 fb-1. The transverse mass distribution of the
selected WZ candidates is found to be consistent with the Standard Model
expectation. Upper limits on the production cross section times branching ratio
are derived using two benchmark models predicting a heavy particle decaying to
a WZ pair.
