  1. Summary on T2 Track Reconstruction Mirko Berretti, Giuseppe Latino (Siena University & Pisa INFN) Software and Simulation Working Group – Collaboration Meeting June 24, 2008 Highlights: • A short summary • We need to better understand high  track selection cuts (as you already know …) 1

  2. Beam Pipe Effect: Secondary Particles Effect of beam pipe (I) : pion hadronic interaction  lots of secondary particles cone section at η = 5.53 Each point = <Tracks> per event firing 1000 - with: E = 50 GeV 0 < f < 2p h- = as shown in x axis 1 cone section at η = 5.3 cone section at η = 4.9 T2 2

  3. Track Efficiency with Different Cut Requirements Strong correlation between Z and  cuts.More detailed studies needed to improve efficiency. 3

  4. Secondaries in T2 from 0 with/without Beam-Pipe Main effects from HF lower border and BP cone at ~5.53 4

  5. Secondaries in T2 from - with/without Beam-Pipe Reduced effect from HF lower border Main effect from BP cone at ~5.53 5

  6. Trk Pt related effects on trk rec. ,  due to MF/BP 6

  7. More studies on MF effects (50 GeV -) We need more studies to improve track recon. efficiency at high  No MF, no BP 7

  8. More studies on selection cuts effects (No MF, no BP) As already seen, main effects from  and DZ cuts (strongly correlated) 8
