V0 Femtoscopy in pPb @ 8.16 TeV

Write something

• V0 Reconstruction Cuts:
  • aa
• Femtoscopy Cuts:
  • High Purity
  • |η| < 2.4
  • pT > 0.2 GeV
  • NV0 >= 2
  • Nmix = 5
  • Daughters with at least 1 pixel hit (remove some contamination)
  • Mass Signal and Sideband are extracted by mass fits (using mean and sigma - see section X)
    • Mean - 2*sigma < Mass Signal < Mean + 2*sigma
    • Mean - 5*sigma < Mass Sideband or Mass Sideband > Mean + 5*sigma
• Padova Selection (remove splitting tracks and duplicated) -> we decide to use that in our analysis
  • cos θij < 0.99996
  • ΔpT < 0.04 GeV
  • Padova cuts require qinv > 0.04 GeV (i will include some plots to show that)
• Daughter Matching (ΔX = xi - xj, where xi and xj are the daughter with the same charge comming from different V0)
  
  • ΔpT < 0.04 GeV
  • Δφ < 0.04
  • Δη < 0.04
  • Compatible with Padova cuts (i will include some plots to show that)
