D0 Level 3 Meeting

1
Level 3 Missing ET Effect of L3Nada and CH cells

• Lee Sawyer

2
Level 3 Missing ET Studies

• Used p13.06.01 version of d0trigsim and l3fCalMEt
• Almost ran out of the box Had to remove
  unpackers/muons from toollist
• Default for offline trigger list CalMEt_PvtxZ
  uses CAL_UNP_NADA
• Default L3TCalMEt.rcp UseCHTRUE
• Runs analyzed
• Used the two runs for p13 certification
  comparisons 170246 (p12) and 170247 (p13)
• Pulled raw files (parts 1 and 4 for each run)
  from SAM
• Due to time constraints, ran over 2000 events for
  run170246, 1000 events for run 170247.
• Can have better statistics next week when I am at
  DØ
• Results are for l3only option of runD0TrigSim

3
For Todays Meeting

• Will compare results with L3Nada on/off
• When L3Nada is on, L3NadaThreshold 3.0001
• L3Nada off gt Changing to CAL_UNP tool instance
• Both CAL_UNP and CAL_UNP_NADA have calib0 (No
  calorimeter non-linearity corrections in this
  study.)
• EtaMax 3.7 in L3TCalMEt.rcp

4
Run 170247 Missing ET
Using CAL_UNP_NADA
Using CAL_UNP

• No, I do not have the labels backwards!
• No, I do not know why the missing ET is worse
  with L3Nada turned on!
• Well, maybe one idea

5
Run 170247 Other Plots
Using CAL_UNP_NADA
Using CAL_UNP

• Phi of the missing ET shows a spike at 2.3 when
  L3Nada is turned on!

6
Run 170247 Other Plots
Using CAL_UNP_NADA
Using CAL_UNP
Scalar ET
Run I Significance

Work in Progress

• Jobs for run 170246 and run 170247 (no Nada, No
  CH) were still running gt No results today
• This was done in a hurry, may have made a stupid
  error.
• Will have a more complete set of plots for next
  weeks meeting.
