TEST of BCAL reconstruction using pi0
- Pi0 are generated at 50 degree emanating from the target 360 degree in azimuth.
- Three different reconstruction codes are used:
- _KLOE_ currently default algorithm
- _MATT_ algorithm developed by Matt Shehperd
- _JLAB_ algorithm developed by Beni Zihlamnn
- The following plots show that the _MATT_ and _JLAB_ algorithm give very similar results with the _MATT_ algorithm performing slightly better. There seems to be something inherently going wrong with the _KLOE_ algorithm.
- File:GeneratedPhotons.pdf Generated Photons from pi0 decay.
- File:ReconstructedShowerMultiplicity.pdf Reconstructed neutral particle multiplicity for all three algorithms.
- File:AllReconstructedPhotons.pdf All reconstructed photons from all three algorithms.
- File:HighEnergyReconstructedPhotons.pdf The higher energy photon (of the two) reconstructed from all three algorithms.
- File:LowEnergyReconstructedPhotons.pdf The lower energy photon (of the two) reconstructed from all three algorithms.
- File:HighEnergyPhotonsPull.pdf (E_gen-E_rec)/E_rec of the higher energy photon for all three algorithms.
- File:LowEnergyPhotonsPull.pdf (E_gen-E_rec)/E_rec of the lower energy photon for all three algorithms.
