SLIDE 2

CC fitted Multi-track event

Multi-Track 1 track

SLIDE 3

Multi-track event (15.16-16.15 GeV)

No cut on nTrack and nShower No cut on nTrack, nShow = 1 Ntrack = 1, nShow = 1

Comparison of ESEV3 and TRDlik

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

SLIDE 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 ?
