2.6 fb-1 Analysis Summary and Changes since Last blessing
  1. Add p12-p17 data (high lumi) and drop p0 data (low lumi). This change has the following consequences:


  2. Switch back on vertex swap procedure to remove wrong vertex and met cleanup cut to remove tri-pho events. Use ignal MC based on Pythia Tune-A plus Min Bias---> smaller, but more realistic, which also fixes the bug where we estimated the background using the vertex swap and Met cleaunup cut, but couldn't put these cuts on the GMSB signal MC
  3. We re-optimized after these changes and found that only the &Delta&phi cut needed to change and confirmed that vertex swap and Met cleanup cut improve the sensitivity and are needed.

Comparison of MC based and Data based for QCD estimations


N-1 MetSig (MC based) N-1 MetSig (data based)

N-1 MetSig plot based on MC QCD diphoton sample shows that QCD prediction doesn't agree with data very well while The data based prediction agrees better (Here we need to add tripho and wrong vertex template for data based QCD prediction).
The reason is dphi wasn't well modeled in Pythia QCD diphoton MC sample for dphi < 1.5 since it has no fragmentaion contributions, which is known issue. See below plots, which shows QCD predictions based on both data and MC for pre-selection sample (before optimal cuts). The dphi prediction based on MC is very different. Overall data based predictions agree with data better.

MetSig for pre-sample (MC based) MetSig for pre-sample (data based)
Ht for pre-sample (MC based) Ht for pre-sample (data based)
&Delta&phi for pre-sample (MC based) &Delta&phi for pre-sample (data based)

I suggest that we should switch back to the method of QCD prediction based on data as we did for the blessing and add triphoton and wrong vertex estimation separately.

2.6 fb-1 Analysis Summary and Changes since Last blessing
  1. Add p12-p17 data (high lumi) and drop p0 data (low lumi). This change has the following consequences:

    • a) In 2.6 fb-1 (1.0 fb-1 added to and 0.4 fb-1 removed from 2 fb-1 data for the last blessing) analysis, all data has EM timing---> more simple and efficient cosmics and BH rejection.
      b) Higher instantaneous luminosity means that the number of vertices per event will increase---> larger contribution due to "wrong vertex" ("wrong vertex" depends ~linearly on Inst. lumi)
      c) Add Pho50,70 triggers to recover loss in efficiency at high Et(pho)---> due to our Ht cut, this will lead to larger number of ele-pho data events passing the analysis cut and, as a consequence, larger electroweak (EWK) scale factor---> larger EWK bckg

  2. Switch back on vertex swap procedure to remove wrong vertex and met cleanup cut to remove tri-pho events. Use ignal MC based on Pythia Tune-A plus Min Bias---> smaller, but more realistic, which also fixes the bug where we estimated the background using the vertex swap and Met cleaunup cut, but couldn't put these cuts on the GMSB signal MC
  3. Use MC based estimate of the total QCD background (data-based QCD estimates before)
  4. We re-optimized after these changes and found that only the &Delta&phi cut needed to change and confirmed that vertex swap and Met cleanup cut improve the sensitivity and are needed.

To-do list and differences in 2 fb-1 and 2.6 fb-1


1) Difference between 2 fb-1 and 2.6 fb-1 analyses.
    i) add p12-p17 data (high lumi) and drop p0 data (low lumi). This change has the following consequences:
      a) In 2.6 fb-1 analysis, all data has EM timing---> more simple and efficient cosmics and BH rejection.
      b) will increase---> larger contribution due to "wrong vertex" ("wrong vertex" depends ~linearly on Inst. lumi).
      c) added Pho50,70 data to recover loss in efficiency at high Et(pho)---> due to our Ht cut, this will lead to larger number of ele-pho data events passing the analysis cut and, as a consequence, larger SFewk---> larger EWK bckg.
    ii) Use signal MC based on Pythia Tune-A plus Min Bias---> smaller, but more realistic signal acceptance.
    iii) at least up to now, we didn't use vx-swap and met-cleanup cuts in 2.6 fb-1 analysis. It looks like these methods were used for blessed 2 fb-1 results
      a) because we don't use vx-swap and cleanup cuts, the "wrong vx" and "tri-pho" contributions are larger
      b) we use MC based estimate of the total QCD background (can switch back o data based estimate if vx-swap is used again)
2) List of things "to do". I put analysis and documentation in two separate groups, but they should be pursued in parallel, if possible.
    A) Analysis issues; (some things may be done in parallel, order may be changed)
      i) SFewk for all sets of cuts (especially looser cuts);
      ii) update acceptance/efficiency table for GMSB;
      iii) apply "old" procedure of combining Pythia EWK samples to reduce stat uncertainty;
      iv) systematics on QCD: due to uncl. parameterization; JES.
      v) first analysis pass to check "old" optimization;
      vi) test vx-swap and met cleanup with Pythia dipho samples;
      vii) test vx-swap and met cleanup with GMSB sample;
      viii) check other ideas to reduce background: correlation of dPhi's.
      ix) make decision regarding the analysis improvements; re-run optimization if necessary.
      x) address systematics due to ces_chi2 cut.
    B) Documentation;
      i) Finalize public note on 2 fb-1 results, update numbers and text.
      ii) Public webpage for 2 fb-1 analysis should be sent to conveners.
      iii) Update the analysis note for 2.6 fb-1.
      iv) PRL draft

    gg+Met meeting


    1. Calculator
    For the limit calculator we decided to use Tom's calculator for the observed limit since it's standard at CDF.
    2. tune-A MC sample
    To make sure whether the difference in entry 10/06/08 comes really from systematic or statistical fluctuation we decided to generate a larger sample (over ~100k).
    3. Adding 3 fb-1 data
    We plan to go with current result (2 fb-1) for PANIC until Sasha's finishing 3 or more fb-1 and dropping the first 400 pb-1 data and recalculating scale factors. Meanwhile I'm finishing up sytematic studies.
    4. Photon ID efficiency
    I'll review the recenct studies on Photon ID efficeincy.

    Expected Cross Section Limits VS Background Uncertainties after fixing bug


    Background Prediction=0.62

    The limit calculator couldn't handle the case for large uncertainty. Using lognormal distribution for backgroudn prediction from pseudo experiments instead of normal Gaussian resolves this difficulty and also imporoves limits(Thanks to John Hobbs).
    The reason why the limit is lower for using lognormal distribution for the background (in case sigma_bkg/bkg is large) is because the shape of the lognormal in the region near bkg=0 gives a higher bkg than does the gaussian.

    1. Met Model Parametrization is irrelavant for old analyses.
    2. Pile-Up Effect on MetSig is irrelavant for old analyses since the met model is NEW.
    3. PDFs for previous gg+Met uses 5 MRST sets, but 20 CTEC-5L sets were used for delayed photon analysis. We're currently using the same sets as in delayed photon analysis.
    4. ISR/FSR difference : ask Ray.
    5. Photon ID efficiency for gg+Met is almost twice as delayed photon analysis since it has two photons in final state.

    Their patterns are depending on their prediciton values in three different regions: prediciton < 1, 1 < predition < 2, and prediction > 2.
    i) For prediction < 1: They look like having minimum around Prediction value and getting worse as the uncertainty goes far away from it and worst at 0 uncertainty for background prediction < 0.
    ii) For 1 < prediction < 2, They just fluctuating..I don't know.
    iii) For prediction > 2, They get worse as uncertainty gose up and have munimum at 0 uncertainty.
    It turns out that these are from low statistics on pseudo experiment. Please see the first and 3rd plots.

    Optimal Cuts: HT > 200 GeV, with MetSig > 5.0
    This is even better than with Et(pho1)>20 GeV in entry 08/05/08. This means that Ht cut is optimizing better without Et(pho1) cut. Et(pho1) is correlated with Ht. How? See here. This plot shows the ratio, Ht/Et(pho1) with ONLY MetSig>5. The ratio is greater than 2. For example, given Ht>200 GeV cut, Et(pho1)>30, 40, 50, ...GeV make no differences.

    EMTiming Distributions of photons for GMSB signal(m&chi=100 GeV, &tau&chi=0 ns)


    Ph1_EmTime Ph2_EmTime &Delta t (&gamma1,&gamma2)

    - These plots show EmTiming distribution after EMTiming cut(before vertex swapping).
