Settings 2A/B1723 and 3A/B 1723 are analysed with: Flat RICH eff (97%) (not using parametrised eff) p, pbar are corrected for RICH contamination (3%) nkv2 file for tracking eff. Using XA. Newest geant files with cut factor 4 for FS. Chi square cut that removes a small fraction of tracks on Const*(A+B/p) formTRANSCRIPT
Last checks of pp 62 FS
A.Qviller
Settings 2A/B1723 and 3A/B 1723 are analysed with:
• No CC vtx. Normalisation towards total CC yield within -60+40 times a factor of 3.
• Vtx bins 5 cm, 2% accmaps• RICH cut X=+-20 Y=+-15. Back of T5 cut (Y=+-
14)• Fixed 6 sigma cut on back projected y-vertex. • Require trigger 2• Bins with less than 0.6 factor of average
acceptance are removed
Settings 2A/B1723 and 3A/B 1723 are analysed with:
• Flat RICH eff (97%) (not using parametrised eff)
• p, pbar are corrected for RICH contamination (3%)
• nkv2 file for tracking eff. Using XA.• Newest geant files with cut factor 4 for FS. • Chi square cut that removes a small
fraction of tracks on Const*(A+B/p) form
Status of analysis
• MRS analysis is within 5% with FV, considered ok.
• FS spectra in the interval ~6-8% below FV analysis dated 2007-10-29
• Seems to be species independant (k- and p have also been inspected)
Pi plus
Pi minus
Slat 24 is poor in all settings
PID seems ok (2B1723)
Inefficient (blue) area in front T5
