This week's data

6ish pb-1 are coming (some discussion still about run 147755).

Last week's data:

all 4150nb-1 is finished. It had to be run without the bit 40 or 41 that most data up till now has been processed with. please check your selection yields/pb-1 and check these triggers.

/raid1/yma/MPAfiles/MPA_Run2010B_oct22_4140nb.root <- please analyze me

4150nb-1 coming in Run2010B:

now that the files are getting large and precious, they will be placed in hadoop (redundant backup).

Current open studies/issues

  • Z yields in EE/EE and EB/EE pairs
  • Z mass shift due to Endcap transparency change
  • high mass diphoton pairs (add R9 cut)
  • high mass gammaJet pairs (event displays)
  • effect of preselection (no TT bits, adding a sample with a beam scraping filter)
  • diphoton rate in data, week to week

previous data:

up to oct15th JSON

7875nb-1 in Run2010B.

3068(3049)nb-1 in Run2010A(old partial) file.
