IFR R14 vs Converted-SP5/SP6 Data/MC Comparisons
This page contains data/MC comparison plots made using a muon control sample (BtamumugamaSample in the
BetaPidCalib package) taken from the R14 data and converted SP5/SP6 mu-pair events from the "e+e- -> mu+mu-gamma (KK2F)"
samples. Both data and MC are required to pass the BetaPidCalib selector for consistency. The muon tracks
selected are unbiased with respect to PID information from the IFR and EMC. The MC is divided into monthly
blocks determined by the CONDALIAS with which it was generated. It is compared with data taken from runs only
during the same period that the MC is intended to simulate.
Muon Track Comparisons
The first set of plots show comparisons (for each muon track) of:
- Track polar angle in the lab frame
- Track momentum in the lab frame
- associated EMC energy
- number IFR layers hit
- number of 1D clusters associted with the track
- number of 1D clusters divided by the number of layers hit (expect 2 in general, 1 per view)
- number of fired strips associated to the track
- first layer hit by the track
- last layer hit by the track
- last layer hit by the track in the barrel
- measured number of interaction lengths traversed (lambda)
- expected number of interaction length traversed
- delta lambda (measured-expected interaction lengths)
- number of interaction length traversed before reaching IFR
- continuity ((last layer hit - first layer hit) /total layers hit)
- cluster fit chi2/dof
- track match chi2/dof
- number of degrees of freedom of the track match chi2
- total number of strips fired divided by the number of layers hit
- standard deviation of the distribution of number of strips fired per layer
- highest passed muon ID (micro Selector) (minI=1, veryLoose=2,loose=3,tight=4,veryTight=5)
- highest passed muon ID (NN Eff Selector) (minI=1, veryLoose=2,loose=3,tight=4,veryTight=5)
- highest passed muon ID (NN Fake Rate Selector) (minI=1, veryLoose=2,loose=3,tight=4,veryTight=5)
- number of components making up the IFR cluster (~number of IFR sectors traversed by track)
- number of 2DClusters making up the IFR cluster (~2 x number of IFR sectors traversed by track)
Each page shows four plots which are (i) tracks with hits in forward EC only (ii) tracks with hits in forward EC
and barrel (iii) tracks with hits in barrel only (iv) tracks with hits in backward EC and possibly barrel. The
histogram is MC and the points are data. The plots are normalized to the same area.

Muon ID Efficiency Comparisons
Using the same data described above, the following plots attempt to determine where the discrepancies
in muon ID efficiency originate. For each month and for each region of the IFR defined above
(FWD, Overlap, Barrel, BWD), we plot the efficiency to pass each of the cuts in the veryTight micro selector
as a fuction of track momentum. The cut being applied is listed on each plot. The blue is MC while the black
is data. The last two pages show the efficiency to pass all previously plotted cuts and the efficiency to pass the
veryTight selection. These two should be identical (but in fact there are some small differences). It's just a
cross-check to make sure my cuts in ROOT are the same as those actually applied by the selector.
