High mass 'Twin peaks' in HYDJET+Z mixed sample

Problem

• while running on
• Illustration
• cfg that produced the data sample: 2 issues

Approach

• Idea
• Data sample production
• Sanity production

Summary

• Tabels with different channels

Conclusions

• found the contributors, the question is why it appears in the production sample; channel,
• check:
  • other, hi-central produced minbias samples
  • look in hiSignal and generator separatelly (embedded signal and background only respectively)
  • 'ditrack' invariant mass
  • mismatch between si-track and sta-muon --- run separately sta and si-trk matching, and compare concomitently with the glb-matching
