  1. Tagging jet W Z/W H Z/W W Tagging jet Central Jet Veto Efficiency And Multiple Interaction Models • The VBF signal is (HWWll) • Central Jet Veto - A cut on events with secondary jets occurring with Pt > 20GeV/c in the central region |η|<3.2 • Secondary jets can be produced by the Underlying Event leading to signal events being cut by the CJV. • Used PYTHIA with ATLFAST to investigate CJV efficiency for different multiple interaction models. Dan Clements – Feb 2005 Glasgow ATLAS physics meeting

  2. CJV efficiency varies from 68% to 83% between models at 20GeV/c threshold. • Efficiency varies strongly as a function of Pt threshold in CJV definition. • Further research using fully reconstructed events (as opposed to ATLFAST and ATLFAST-B) Dan Clements – Feb 2005 Glasgow ATLAS physics meeting
