Status on positron fraction Multi-track event CC fitted Multi-track - PowerPoint PPT Presentation

Status on positron fraction Multi-track event CC fitted Multi-track event 1 track Multi-Track Multi-track event (15.16-16.15 GeV) No cut on nTrack and nShower Ntrack = 1, nShow = 1 No cut on nTrack, nShow = 1 Comparison of ESEV3 and TRDlik


  1. Status on positron fraction Multi-track event

  2. CC fitted Multi-track event 1 track Multi-Track

  3. Multi-track event (15.16-16.15 GeV) No cut on nTrack and nShower Ntrack = 1, nShow = 1 No cut on nTrack, nShow = 1

  4. Comparison of ESEV3 and TRDlik 10-20 GeV No cut on nShower TRDlik ESEV3 One track Multi track Proton Proton 96 % 4 % Proton Lepton 96 % 4 % Lepton Proton 40 % 60 % Lepton Lepton 88 % 12 % Nshower == 1 Lepton Proton 63 % 37 %

  5. Conclusion ● Discrepancy versus ESEV3 and TRDKlik increased by multitrack and nShower ● It can be explained just by a merging of two shower ? ● How reduce this discrepancy ?
