         1. To prepare presentation files for HI meeting of 11/Jan/2008
            i. To show generation information(eta, pt) using module, genParticleCandidates
               * Displaced muons preselected by dimuon filter in the region of |eta| < 2.4? -> %ORANGE% I think so. But more statistics are needed(more than 3000 events) for sure. %ENDCOLOR%
               * muons/bastMuons(1000events) = 0.81 -> muons/bestMuons(3000events) = 0.9 : %ORANGE% What does this mean? I think if I increase number of events, muons/bestMuons ~ 1. %ENDCOLOR%
               * The order of path effects the results or not?  -> %ORANGE% NO EFFECT!! %ENDCOLOR%
                  A. path p1 = { mumufilter, genParticleCandidates, psim, pdigi} = { mumufilter, psim, genParticleCandidates, pdigi}
                  A. genParticleCandidates is also produced by reconstruction 
            i. With this sample, HLTriggering was excuted.

      * Presentations in HI fortnightly meeting
         1. ppts ([[%ATTACHURL%/SecondaryJpsi_11Jan08.pdf][SecondaryJpsi_11Jan08]])
         2. Olga asked me why there were 2 peaks in Pt spectra of generated muons

         1. Comparing 2 events
            * B3000_JPsifilter_dimuonfilter(|eta| < 2.4)_genParticleCandidates : For studying JPsifilter removes 1 peak in pt spectra of generated muons
               * Using /net/hisrv0001/home/jkim/CMSSW_1_5_4/src/Bevents/GEN_DIGI/BBar2Jpsi_digi.cfg  <verbatim> /net/pstore01/d00/scratch/jkim/b3000_FEVTSIM_genCand_jspidimufil.root </verbatim>
            * B1000_dimuonfilter(|eta| < 10.0)_genParticleCandidates : For studying dimuonfilter preselects displaced muons or not
               * Using /net/hisrv0001/home/jkim/CMSSW_1_5_4/src/Bevents/GEN_DIGI/BBar2Jpsi_digi_nopresel.cfg <verbatim> /net/pstore01/d00/scratch/jkim/b1000_FEVTSIM_genCand_dimufil_nopresel.root </verbatim>

         1. Comparing preselected and non-preselected 1000 events(only use dimuonfilter)
            * In the case of preseleceted, bestMuons/muons = 2923 / 3227 = 0.81
            * In the case of non-preselected, bestMuons/muons = 2429 / 3693 = 0.66
            * -> %RED% My conclusion : %ENDCOLOR% Preseslection by dimuonfilter is working, but the percentage of preselection by dimuonfilter is not 100%. But I guess if statistics is larger than 3000, maybe bestMuons/muons will be ~ 1. 
         2. B3000_dimuonfilter(|eta| < 2.4)_genParticleCanddates : For studying difference with genParticleCandidates and Reconstruction   
            *  Using /net/hisrv0001/home/jkim/CMSSW_1_5_4/src/Bevents/GEN_DIGI/BBar2Jpsi_digi_presel.cfg <verbatim>/net/pstore01/d00/scratch/jkim/b3000_FEVTSIM_genCand_dimufil.root</verbatim>
         3. Making QM08 poster using by Adobe Indesign CS3
                    
   * 25 Jan 2008
      * CMS HI meeting : QM'08 rehearsal
         * Comments from Olga and David 
            1. Generate more 'B-> only J/Psi-> only mu+mu-' events(~100000)
            2. Apply cuts( |eta|<2.4, Pt>3.5) for the CMS
            3. Gaussian fit and scale up
               * Gaussian (or 2-Gaussian) fit to dN/deta, scaled-up to match expected yield for 0.5 nb-1 (note that you have to scale p-p to Pb-Pb, multiplying by 208*208, and then by 0.5 nb-1)
            4. extend Pt range
               * Ideally the pT reach should match the expected statistics for 0.5 nb-1. So you will have to fit the dN/dpT with a power-law to extend the tail beyond your generated events.
            5. Normalize y-axis with nominal luminosity like Fig. 7
