Prospects of measuring ZZ and WZ polarization with ATLAS detector

Draft slides for talk on July 29 at the "symmetry and spin 2009” conference: http://theor.jinr.ru/~praha/2009/ We review the prospects for W or Z polarization measurements in diboson channel (ZZ and WZ) at the ATLAS detector with 100fb-1 data , focusing on expected polarization measurement result , technique we use to extract W or Z polarization information from decay product of W or Z , and Event reconstruction technique in WZ channel (lepton decay angle and reduced center of mass reconstruction) . Background estimation and systematic uncertainties study are also summarized in the talk.
