          Data collected during Run13 were made with luminosity almost three times greater than the previous year, which represent more statistics but also new challenges to handle this increase in luminosity.  

 

Run 2013 data is divided in 2 periods:

- Period 1:  is subdivided in four parts, due two trigger setting changes and after run 14102029 TPC voltage was changed from 1390V to 1345V (see ref .1 for details). 

- Period 2: insertion of the HFT on the east side (η < 0), after run 14129023. The extra material caused modification to some average parameters of the jets.

 

            The total list of runs is given at /star/u/aquinter/Jets2013/Preliminary/AllRun13.list, which are 1601 runs without any QA, where 931 are for period 1 and 670 for p2.  

 

1.- Jets trees:
            Working directory : /star/u/aquinter/Jets2013/Preliminary/JetTrees

            Library: SL17a

 

Jet trees are produced from the official run 13 MuDst files. The folders are needed to submit the production:

• StRoot: with the appropriate trigger definitions for run 13 (see ref. 2).
• macros: get MuDst and outputs jets, skim, ueCones and ueRegions .root.
• submit: need select the run list and change the output location. To submit the list > sh submit_jetsProd2013.sh
• HPSS: to upload the jet files to HPSS (if needed). Need to modify the QA_runtar.job with the proper location and the number of files in the list (at the end of this file). To submit > condor_submit QA_runtar.job.

 

2.- Inclusive Trees:
            Working directory : /star/u/aquinter/Jets2013/Preliminary/IncTrees

            Library: dev (latest one SL17a)

            The inclusive trees are produced from the jet trees:

• StRoot: the main class is StIncJet2013Event, which has all the information of the reconstructed trees.
• macros: the main propose of this code is to match the jets to a Jet Patch (JP). This also assigns the polarizations.
• submit: need select the run list and change the output location. To submit the list > sh submit_IncJetTree.sh.
• compile: compile the macros (change the location) > ./compile.

            

3.- Histograms:
           Working directory : /star/u/aquinter/Jets2013/Preliminary/Histograms

            Library: dev (latest one SL17d)

             After the inclusive trees are produced, need to produce the histograms of the relevant jet quantities per run:

• MakeHistoUEv5.C: reads the Inclusive Jets tree and save the information in ROOT histograms 
• runHisto.sh: shell script to run the MakeHistoUEv5.C. Needs the run list with the relative luminosity; in the folder ../RelLumi. These values where calculated following: Readme.txt
• Need to modify the QA.job with the proper location and the number of files in the list (at the end of this file). To submit > condor_submit QA.job.
• Also need to create a “condor” folder and a “Histograms” folder for the outputs.

 

4.- Plots:
           Working directory : /star/u/aquinter/Jets2013/Preliminary/Plots

            Library: dev (latest one SL17d)

 

            Combine all the produced histograms before plotting > hadd test.root Histograms/*

• Plot_JetsUE4.C: plots all jets quantities and A_LL results, also prints the results of A_LL.
• Plot_AvgIdx.C: plot all quantities vs run index 
• Plot_AverageUE2.C: plot all quantities vs zdc, fit a pol3 and print the runs outside 3 sigmas of the fit.
• Plot_UE2.C: calculate the UE asymmetry for systematics.
  
• Plots_Final3.C: plot the final plots. Need to write the results of the asymmetry after trigger bias correction and pt shift; and write the statistical and systematical errors.
• Replicas.py: plot the results with 100 NNPDF1.1 replicas.
