  • manpower survey ?

  • Hydjet root file (2000events) at CERN root -l rfio:/castor/cern.ch/user/s/silvest/rootfiles/HI/hydjet_Summer09_MC_31X_V2_GaussianVtx_311_ver1_2000evts.root
    • I also have a same and an opposite sign di-muon tree

// Loop over all sim products
for(TrackingParticleCollection::size_type i=0;i < simCollection.product()->size(); ++i)
   // Retreive tracking particle reference
   const TrackingParticleRef simTrack(simCollection, i);
    // loop over all HepMC particles which make up this track. In principle there can be more than one
    TrackingParticle::genp_iterator sim_part_it;
    TrackingParticle::genp_iterator sim_part_begin  = simTrack->genParticle_begin();
    TrackingParticle::genp_iterator sim_part_end = simTrack->genParticle_end();
    for (sim_part_it = sim_part_begin; sim_part_it != sim_part_end; ++sim_part_it)
      const HepMC::GenParticle *part = sim_part_it->get();
      // check if particle will reach the muon stations 
      if( part==NULL || abs(part->momentum().eta())>2.5) continue;

hydjetTree = new TTree ("hydjet","Tree of Hydjet Events"); // tree with particle information hydjetTree->Branch("nevt",&nevt,"nevt/I"); hydjetTree->Branch("id1",&id1,"id1/I"); hydjetTree->Branch("eta1",&eta1,"eta1/d"); hydjetTree->Branch("pt1",&pt1,"pt1/D"); hydjetTree->Branch("px1",&px1,"px1/D"); hydjetTree->Branch("py1",&py1,"py1/D"); hydjetTree->Branch("pz1",&pz1,"pz1/D"); hydjetTree->Branch("p1",&p1,"p1/D"); hydjetTree->Branch("status1",&status1,"status1/I"); hydjetTree->Branch("y1",&y1,"y1/D"); hydjetTree->Branch("e1",&e1,"e/D"); hydjetTree->Branch("mass1",&mass1,"mass1/D"); hydjetTree->Branch("part_out",&part_out,"part_out/I");

  • pgun with some code committed by Generator crew is under validation... I'll make the same slides with the fix to see how it behaves. A first check with 500 Z suggest that the low pt region has no more excess but there are still some dimuons (Z) with a pt larger then the initial cut at 20GeV.

  • di-lepton report went well
    • need to continue work on background checks => is hydjet a relevant background for muon studies ?
    • preparing a meeting on muon reconstruction in HI with experts and us for mid-february

  • service work ?

January 20 2010

  • studies ongoing :
    • hydjet studies
    • high pt Z0 embedded in hydjets efficiency

  • upcoming events
    • dilepton meeting
    • dilepton review
    • presentation at lanl
    • Hot quark participation ? abstract ?

January 4 2010

  • News from Dave about the service work ?
  • Application to the CNRS
  • Travel : leaving LANL on thursday 11th Febuary and coming back on Monday 3rd of May ? Will you come for CMS week in march ?

December 16 2009

  • should I keep gathering slides about plots from CMS, lhc news ?
  • service work : Gerd will write to Dave to know how t oget into the trigger team and take trigger shifts

December 14 2009

December 7 2009

  • CERN news: slides summary of cern activity
  • answer Bolek : doing trigger shifts might make sense => see with Dave; UIC should update that I take service work with them; then the service manager will be notified; Bolek says DQM shifts are also service work and should be added automatically to my account of service work
  • no answer from Roberto about his slide 3 : data driven or MC based ? But listening to a talk today I understand that the dada driven estimations may not be feasible when the statistics is too low. This may be the reason...
  • PAT matching : same accessors to matching as RECO, details here
  • I may apply to a CNRS position : what recommendation letter that I had for LANL were good ones ?

December 1 2009

  • discuss GEN slides before posting DONE
  • plans for 2 months
    • analysis wise : ALERT! write scketch of AN with figure captions and send it for discussion to list
      • go through todo list
    • neutron simulations ? or later MOVED TO... later
    • shifts ? RD ? ALERT! write to Bolek to know about service work, and how to sign papers DONE
  • I could send a summary pointing to interesting plots /news every week for monday meeting MOVED TO... to be send every monday
  • talk every wednesday ? what time MOVED TO... mondays and wednesday @17h GVA time @9AM LANL time
  • twiki ? MOVED TO... yes
summary of todos ALERT!
  • write to Roberto to know about slide 3 of his slide : data driven or MC based ?
  • study Dipanwita note AN2007/00, Z->mumu AN2006/082, AN2006/124, arxiv0706.2940v1
  • draft Z0 first year AN : here
  • look at what matching information come from PAT to see if I move completely to PAT or just partly
