nnΛ Analysis Meeting

Information

• 21:00- March 31, 2021 (JST)
• Participants: Nue, Liguang, Pete, Joerg, Franco, Guido, Toshi, Sho, Bishnu, K.N.Suzuki, K. Itabashi, Nathaniel
• via BlueJeans

Reports

(25 + 10 min) Kyoto analysis by K.N. Suzuki

• Resolution study by Geant4 simulation
  • Angle resolution
  • Missing mass resolution
• Systematic error on B_Λ
• Cross section analysis

Discussion

• What needs to be done / checked for the publication?
  • H contamination → Shape of Λ is better to be asymmetry.

• Questions
  • How to estimate
    • the angular resolution?
    • QF Λ shape including the Σ ?
