The systematics (1): Correction factors & syst. errors

• Efficiency losses calculated with 2M simulated single p0 embedded in real data

• Correction factors: x20.- x10.

• • Acceptance: ~1/0.25
  • Efficiency: ~1/[0.20- 0.30]
• Systematic errors (% yield):
• • p 0 extraction: ~15%
  • pT smearing: ~10%
  • TOF cut : ~10%
  • Fiduc., asym., hot towers cuts: ~5%
  • Acceptance: ~3%
  • Off-vertex p0 contribution: ~3%
  • Final systematic error: ~20%- 30% (periph), ~23%- 33% (central) increasing with pT
