Missing Et objects
Reco
All missing Et objects that are available are on this webpage: https://twiki.cern.ch/twiki/bin/view/AtlasProtected/EtMissObjects
General schema: http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/JETS/EMISREC/MET_schema_2.pdf
The default MissingEt object is MET_EtMissRefFinal, which is described in detail here:
https://twiki.cern.ch/twiki/bin/view/AtlasProtected/EtMissRefFinal
http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/JETS/EMISREC/RefFinal_schema_2.pdf
For some purposes it might be useful to use MET_Final, described here:
Truth
MissingEtTruth objects:
Int = all interacting particles till abs(eta) <= 5 (muons excluded)
NonInt = all non interacting particles (neutrinos and SUSY)
IntCentral = interacting particles in abs(eta) <= 3.2 (muons excluded)
IntFwd = interacting particles in 3.2<abs(eta)<=5 (muons excluded)
IntOutCover = interacting particles with abs(eta) > 5 (muons excluded)
- Muons = all truth muons
fixing muon term in r635_t35 samples
