E/p of V0 in Data

Pic_sig_data.png"

  • There are entries E/p < 0.8 (minimum E/p cut in this analysis) in V0 sample in data
  • Indicate there are some hadron contamination in the sample

V0 efficiency comparison between MC and Data

Pic_sig_data.png"

  • Low pT ; Data efficiency is smaller than MC
  • High pT ; Statistically limited but Data is smaller than MC

Pic_sig_data.png"

  • Low pT ; Data & MC is consistent
  • High pT ; Statistically limited but Data is smaller than MC

Summary

  • There are hadron contamination in V0 sample in data.
  • The discrepancy between MC and V0 (data) is the contribution.
