  1. Working Group 5:Particle Identified Studies in Jets- Proposed plots for PPR -

  2. Quality and statistics of jet triggered particle spectra in jet cone Hadron yields Resonance yields needs efficiencies and acceptance, can be extended to include heavy flavor

  3. Realistic plots with error bars for simulations with and w/o quenching Sapeta / Wiedemann

  4. Errors on identified fragmentation functions with and w/o gluon splitting Sapeta / Wiedemann

  5. Errors on jet triggered particle ratios with and w/o gluon splitting Sapeta / Wiedemann

  6. side 1 near away side 2 Errors on resonance properties (yield,mass, width, branching ratio) in jet triggered Df analysis e.g. STAR results:Trigger pT > 4GeV, f(1020) <pT>~ 0.9 GeV All angles In Jet-Plane Same Sidenear M inv (K+ K-) M inv (K+ K-) Out of Jet-Planeside1 + side2 In Jet-Plane Away Sideaway Systematic errors not included ! M inv (K+ K-) M inv (K+ K-)

  7. Necessary information • Not a lot of simulations, more information gathering • Could be done on the basis of scaled PYTHIA spectra or Wiedemann event generator • ALICE information necessary: • Jet cone algorithm and its efficiency (PPR group 1) • Trigger efficiencies (PPR group 2) • rdE/dx resolution (TPC group) • e/p rejection (TRD group) • V0/heavy flavor reconstruction efficiencies (PWG-3 and PWG-2) • Resonance reconstruction efficiencies (PWG-2, maybe TRD group) • Compare to model predictions (recombination, quenching)
