Efficiency x acceptance x Branching ratio for Xi*0 in Pb-Pb collisions determined as the ratio between the number of true Xi*0+antiXi*0 pairs in the selected rapidity interval that are reconstructed and the number of generated Xi*+antiXi*0.
Detail description
Keywords: Xi*0, Pb-Pb, efficiency
Data sample: LHC14a1a, LHC14a1b, LHC14a1c (Monte-Carlo anchored to the LHC11h data sample)
Event selection :

- pseudorapidity, \eta in [-0.8, 0.8]
- number of TPC crossed rows> 70
- \chisquare per TPC cluster < 4.0
- number of clusters in the SPD ≥ 1
- reconstructed pairs rapidity range -0.5 < y < 0.5.
PID cuts:
- Nsigma_TPC < 3
