  1. Status and news Z.Liang

  2. MC11 requests • According to Joao, MC11 production are almost done • There is possibility to ask for more MC11 dataset for rel17 paper • H->WW group is asking for more Wgamma samples • HWW lower limits change from 140GeV to 127GeV by switching to high statistics Wgamma background samples. • They would like to have two times statistics for Alpgen W+gamma+0/1/2/3/4/5 jets samples in one week. • Need help to produce more 4 vector inputs file • Please contact me if you would like to help

  3. The proposal • MC11 extensions proposals: • Alpgen W+gamma Np0 • 1250k ->2120k • Request for Sherpa W/Z+0/1jet aTGC samples. • (20 datasets) 50k -> 250k • MC11 new requests proposals: • Sherpa W+gamma+0/1/2/3 jets • pT(γ)>15GeV, pT(γ)>40GeV, pT(γ)>80GeV • 400k events per channels

  4. MC12 validation • Alpgen with Herwig ++ ,Wgamma+0/1/2/3/4/5 jets : ZL • Need to regenerate all 4 vector input files with new collision energy and new PDF • Need at least one more volunteer in Alpgen validation • Sherpa : Z+gamma+0/1/2/3 jets : Mia Liu • Jet multiplicity by Sherpa in MC11c have larger discrepancy with data. • Need more careful check with MC10b, MC11c and MC12

  5. Rel 16 paper status • Draft 2 is now in the second ATLAS circulation • https://cdsweb.cern.ch/record/1426305? • 6 comments so far • The deadline for comments is tomorrow • The second public reading this Thursday 1pm, please join if you have time: • https://indico.cern.ch/conferenceDisplay.py?confId=179752

  6. 2012 Trigger request • Muon +photon trigger: • The rate for mu18_g20_loose is more than 4 Hz • Switch to mu24_g20_medium (~1Hz) • What is supporting prescaled trigger for efficinecy measurement? • Mu24_g20_loose with prescaled factor 20 • Muon +2photon trigger: • The rate of mu18_2g10_loose (1.6Hz) looks OK. • Wgamma Electron channel • Two photons trigger (EF_2g20_loose1) has been shown in trigger general meeting last week. • Three photons trigger (EF_2g15_g10_loose) will be presented in trigger general meeting tomorrow
