Overview
This page is for the organization and sharing of information about simulations for the Fall 2014 Commissioning data.
General Info
Discussion Items
- Incoherent beam in bggen - simulate by moving coherent peak, check details of rate/shape (Sean)
- Commissioning target geometry in HDDS/sim-recon (Simon)
- Confirm that the simulation of EM background in HDGeant works for this running (Sean)
- What gate should be used?
-
Decide which version of sim-recon should be usedTag new sim-recon version (Mark) -
Nuclear recoil effects for exclusive modes- later studies if needed-
Should we include effects for recoil protons? -
Should we include other recoiling nuclei? (Carbon?)
-
Conditions
- Software
- tags/sim-recon-cs1 (provisional name)
- tags/hdds-cs1 (provisional name)
- JANA 0.7.2
- CCDB 1.02
- 200M bggen events with Solenoid @ 0 A and 1200 A
- Assume unpolarized photon beam 1 MHz/GeV at the endpoint
EM Background Simulations
- What is the background rate with no target?
- What is the background rate with various targets?
Hadronic Event Simulations
Overall hadronic rate

Final States
These reactions can be used either as benchmarks due to their large cross section or are interesting to various subdetectors
- γp→π+π-p

- γp→π+π-π+π-(p)
- γp→ηπ+π-(p), η→γγ
- γp→K+K-π+π-(p)
- γp→K+Λ, Λ→pπ-
