Endcap Electrons
This analysis is based on the work of Jan and Justin on SMD Profile Analysis for different TPC momenta. See here for a list of cuts. The original code used by Jan and Justin is here.
- Transverse running
- Analysis uses 64 out of 300 runs from 2006 pp transverse run
- MuDst are located at:
/star/institutions/iucf/balewski/prodOfficial06_muDst/
- No trigger selection
- Click here for SMD profiles of transverse electron candidates.
- Click here for ROOT file with transverse electrons ntuple.
- Longitudinal running
- MuDst are located at:
/star/institutions/iucf/hew/2006ppLongRuns/
- Click here for SMD profiles of longitudinal electron candidates.
- Click here for ROOT file with longitudinal electrons ntuple.
