A Wrinkle: <strong>Jet</strong> Periphery A Angerami, W. Holzmann High-pT at LHC '09 02/06/2009 • PYTHIA only towers primarily in the jet periphery • Really effects the energy scale • Possible solution: modify the energy scale correction 28
Summary • There are subtleties in the jet reconstruction algorithm in heavy ion collisions – Fake rate from correlate background fluctuations – Modification <strong>of</strong> k T jet shape • These issues can <strong>and</strong> need to be overcome by careful study from data for jet reconstruction to become st<strong>and</strong>ard in heavy ion collisions. • Underst<strong>and</strong>ing <strong>of</strong> the underlying event is crucial to underst<strong>and</strong>ing <strong>and</strong> performing jet reconstruction measurements in heavy ion collisions. – Can we measure, non-jet, correlated background fluctuations?
