Hee analysis status report
Genova team - 21/1/02
Final low mass treatment:
Old analysis |
Present analysis |
Mjets > 20 GeV at preselection |
No such cut |
-50 GeV<Mjets(4C fit) - Mee(4C fit)<100
GeV |
Mjets(4C fit) - Mee(4C fit)<100 GeV |
Mjets(4C fit) + Mee(4C fit) >150 GeV |
Mjets(4C) + Mee(4C) >100 GeV if Mjets(5C)
<60 GeV
Mjets(4C) + Mee(4C) >150 GeV if Mjets(5C)
>60 GeV |
Effect on Hee samples: good efficiency
from low masses (plot)

CONCLUSIONS:
-
essentially final analysis (?)
-
input ntuples for limit derivation already available
-
study of systematics not yet performed
-
publication "details" to be agreed (text, figures, tables)
