Analysis Details

• Exclusive reconstruction of the pbar p -> D_s D_s0(2317) (might be an efficiency problem)
• Inclusive reconstruction of the recoiling D_s
• Determine the production cross section of this reaction by performing an energy scan in the threshold region (real data only!)
• Determine the width of D_s0(2317) from the shape of the excitation function

• Target of physics booklet analysis
  • reconstruct signal events in either way given above and determine efficiency
  • determine background level with DPM events (maybe chosen explicit bkg channels...)
  • assume particular signal cross section for signal/bkg
  • simulate the measurement of excitation function (appropriately mix constant bkg with expected number of signals and fit the signal)
  • determine, how much data taking needed to exctract width with 3 σ significance

Decay Modes

Background Channels

• DPM
• non-resonant pbar p -> D_sD_sπ⁰
