The plots shown here are from NA62 2016 data and are produced by modifications of code written by Giuseppe Ruggiero and Connor Graham.
The plots show comparisons of data with MC
K+ -> mu+ + nu and
K+ -> pi+ + pi0
Data - black, MC - green. Plots are shown only when there are entries in both data and MC.
The plots are mainly those coded by Giuseppe and Connor.
COMPARE WITH MUON CHANNEL
-------------------------
Muon Channel, KaonEventAnalysis
Muon Channel, KaonEventAnalysis: projections of scatterplots
There are small differences in Plots 1, 6, 28 , for K+ parameters.
Why holes in plot 4 ?
Good agreement ( apart from small tails in data) for missing
mass to muon (plot 222).
The straw plots show some differences between MC and data, see 249 onwards.
In particular, the MC ( 250 , 255) shows peaks that are not present
in the data.
Muon Channel, TrackAnalysis
Muon Channel, TrackAnalysis: projections of scatterplots
Why is ltest (64) different between data and MC?
Muon Channel, OneTrackEventAnalysis
Muon Channel, OneTrackEventAnalysis: Projections of scatterplots
The majority of discrepancies are probably due to the difference in event multiplicity
between data and MC.
Data has strong K+ peak - plot 64.
Muon Channel, TwoPhotonAnalysis
Muon Channel, TwoPhotonAnalysis: Projections of scatterplots
Nothing of particular interest.
COMPARE WITH PION CHANNEL
-------------------------
Pion Channel, KaonEventAnalysis
Pion Channel, KaonEventAnalysis: projections of scatterplots
Pion Channel, TrackAnalysis
Pion Channel, TrackAnalysis: projections of scatterplots
Pion Channel, OneTrackEventAnalysis
Pion Channel, OneTrackEventAnalysis: Projections of scatterplots
Pion Channel, TwoPhotonAnalysis
Pion Channel, TwoPhotonAnalysis: Projections of scatterplots
Plot 22 TwoPhotonAnalysis/Clusters_all_time: no timing for LKr?
Plot 26 TwoPhotonAnalysis/MipClusterEnergy_zoom: small shift.
Plot 29 TwoPhotonAnalysis/EMClusterEnergy: energy shift?
Plot 40 TwoPhotonAnalysis/TwoEMClusterTime: width differs.
