A0xy study

A0 effect estimate using MC of HF

  • This requires as input my Ntuple files ("tree_ NTUPTree"), while for the impact on BDT it requires "bdtTree_ / finalTree" files.
  • As it requires high statistics, I used full AugOnly derivation, removing triggers
  • The input AOD samples are produced by Olya, on the basis of the (so far) available RDO files for HF->tau->3mu MC.

with the addition of the option

--postExec \
'from IOVDbSvc.CondDB import conddb;' \
'conddb.addOverride("/Indet/Align" ,"InDetAlign_R2_2016postTS1_d0biased" );' \
'conddb.addOverride(/TRT/Align" ,"TRTAlign_R2_2016postTS1_d0biased" );
  • The DAOD can be found here: /data/atlas/users/mbedog/Olya_RecoToAOD under deriv_mod_all and deriv_orig_all .
  • When making the "tree_" files I only require Truth matching, and particles to be reconstructed as muons (with ID- track).
  • Plus the selection Truth pt > 2.5 GeV and |eta| < 2.5
  • For the bdt impact one of course needs to add the BDT response to the files using update_ntup_withBDT code
  • The code to make the difference plots is FriendTree.cxx in Bias_Impact folder on my desktop
  • Options are hard-coded inside it
  • I need to improve the plots it produces using the style and adding labels to axes

Jpsi Study Instructions (OLDER)

To replicate the study one needs my framework.
It needs to produce ntuples on BPHY1 derivation, which will then contain triplets where the 3rd muon coincides with the 2nd.
All plots of interest are going to end up as JPsi plots.
For the PLOTTING script one needs to add to the "fl" file fits: yes
jpsi: yes
The first option will lead to fitting of all a0/d0 variables and significances with a gaussian, and the fit paramteres are stored in a small TTree in the output folder. Two root macros can be run on this, to make comparison plots (also dumps the canvases into a root file, for further manipulation).

I wrote it twice!!

Requires my basic framework to be run on BPHY1 derivation.

This generates ntuples with a triplet where 2nd and 3rd muon are the same one. Correct plots are stored as JPsi... For PLOTTING one should add the settings to "fl":

jpsi: yes
fits: yes

The second performs a fit of the interesting d0 and a0 variables and relative significance. Fit parameters are stored in a special minitree int the output folder, named "FitParameters.root". To plot these values I put 2 root macros on gitlab: https://gitlab.cern.ch/mbedogne/jpsi_plotting

This is the version I used to make plots for Olya in November 2017.
