Simulation tasks/goals for Exclusive Reactions
- DVCS reconstruction resolution:
- 1. Delta^2 = (k-k’-q’)^2: “Electron Method”:
- a. Independent of ion beam 3-momentum spread
- b. Independent of far-forward acceptance
- c. Delta^2 or Delta_perp^2 ?
- 2. Proton (MILOU or TOPEG)
- a. 10 x 275
- b. 5 x 100
- c. 5 x 275
- 3. 4He (TOPEG)
- a. 5 x 100 GeV/u
- b. 10x 275*Z = 10x 137.5/u
- 1. Delta^2 = (k-k’-q’)^2: “Electron Method”:
