  1. EtMiss/ Analysis onFDR2 AOD/DPD data D. Cavalli, S. Resconi, W. Davey

  2. Goal and strategy Our goals: • First look at EtMiss/tau, then "find" Z events Our strategy: • Run TauDPDMaker with Ganga on FDR2 AOD (POOL) data distributed on the 4 T2 IT sites: • to get DPD1 (POOL) and DPD3 (ROOT) data at MI T2 • Run ARana on same AOD and DPD1 events in MI T2: • to check results between the 2 different formats • to get final results/plots • Start to run on Egamma stream, later on run on the other streams: Muon, Minbias, Jet

  3. What did NOT work  used release 14.1.0 on MI UI: • Some time spent to succeed in compiling ARana : • needed 20+ tags to compile ARana (~ 4h compilation time !!), libg2c was missing on the MI UI • RFIO problem to read data with ROOT 5.18.00 : • Savannah bug posted by F. Prelz (https://savannah.cern.ch/bugs/?37691) • TauDPDMaker problem in producing DPD3(ROOT) from DPD1(POOL) : • problem reported to hn-atlas-tauwg, D. Cote is investigating • it works commenting tau • Problems in running Ganga from Mi UI  : • installation went well but problem in setting Atlas release inside Ganga, not much time spent on that, still to be investigated…

  4. What worked  used release 14.1.0: • Run TauDPDMaker with Ganga (on lxplus): • Initial Ganga script thanks to Leonardo C. • sent jobs to the 4 IT T2 sites: • running on all Egamma AOD stream • copying the output DPD1 to Milan SE • This is one of the first attempt to run TauDPDMaker on the Grid (provide some instructions on the TauDPDmaker wiki) !! • Run ARana (on MI UI) on input FDR2 AOD and DPD1: • Modified version by Will to switch between different data formats (AOD, DPD1(3), CBNT) • It worked just commenting MCTruth and jet • A/Z analysis by Donatella in UserAnalysis • some prelimar plots from Egamma stream AOD data

  5. Preliminar plots on the MI sample of: fdr08_run2.0052293(4,5).physics_Egamma.merge.AOD.*** No cuts applied

  6. Preliminar plots on the MI sample of: fdr08_run2.0052293(4,5).physics_Egamma.merge.AOD.*** EtMiss_RefFinal EtSum_RefFinal No cuts applied

  7. Preliminar plots on the MI sample of: fdr08_run2.0052293(4,5).physics_Egamma.merge.AOD.*** mT(lept,EtMiss): 1 selected electron EtMiss  20 GeV Invariant  mass: + 1 selected tau Invariant  mass: After the Z analysis cut flow

  8. Next Steps • Re-do the entire exercise on the new FDR2 data (full statistics) • Use Ganga installation in Milano to submit TauDPDMaker and ARana (?) jobs over the italian Grid. • Produce comparison plots on same events from FDR2 AOD and DPD1 (they should give the same results after the cut flow!!)
