Analysis Details

  • Exclusive reconstrucion of the decay pbar p -> ΦΦ -> 4 K
  • cross section of non-resonant channel around 3-4 μb in ROI
  • separation of resonant ΦΦ on top of non-resonant only possible with PWA (not in scope for physics booklet)

  • Target of physics booklet analysis
    • reconstruct exclusive channel
    • determine efficiency dependent of decay angles of Φ and pbar p-System and proof, that there are no acceptance holes for a later PWA analysis
    • assume particular signal cross section
    • determine, how much data taking needed to measure ξ(2230) with 10 σ significance

Background Channels

Added:

>
  • DPM events (most likely not very relevant)
  • most background will be non-resonant ΦΦ. Since the signal is also produced non-resonant, no production needed
