133029 – 133336 Additional Study

133036

133036• Higher CaloSumET. • Higher EM fraction etc.• Jet eta distribution different• The trigger table is different for this

run /cdaq/physics/firstCollisions10/v3.2/HLT_7TeV/V1 (In earlier runs and later runs, /cdaq/physics/firstCollisions10/v3.1/HLT_7TeV/V1)

Alca_ECAL PhiSym dominates in 133036

Change of DQMplots may bedue to HLTchange.More Alca_EcalPhSym More Ecal energy

133036• Look at Low Pt Jet trigger (HLT_L1Jet6U) only.

133082

133082

• Noisy area around iphi~60 and ieta~20.

133082

• Is it coming from 337-522??? To be confirmed. Until it is confirmed, mark it bad…

133161

133161• Everything looks fine for Calo jets. Tracking not good (i.e. Pf, JPT, TcMET not good) though.

133250

133250, 133269, 133270• Bad tracking and B-field off. Similar trend in all these runs. Mark bad.

133336

133320, 133321, 133324, 133336• What is going on? “Uncleaned” jet

distribution look problematic, but see next page

133320• Cleaned (passing ID) AntiKt jets look fine.
