Update 03.07.2018 -- Run 9 pp: Efficiency, Adjusting DCA, IdVxEnd, and PID Selection
Previously, I was looking into why our tracking efficiency in the Run 9 dijet embedding was so low. We were expecting somewhere between 85~90% for high pT, but we were seeing ~80% or less.
Update 03.06.2018 -- Run 9 pp: Efficiency, Varying Partonic Pt
Update 03.05.2018 -- Run 9 pp: Efficiency, Applying Vertex Cuts
The efficiency calculated in the last post of this study came out to be lower than expected:
Update 03.01.2018 -- Geant Tracks Vs. MC Tracks
I was looking into the differences between the tracks contained in the '*.geant.root' files (which I call "geant tracks") and the tracks contained in the 'StMuMcTrack' branch of the '*.MuDst
Update 03.01.2018 -- Run 9 pp: Efficiency Test
I tried calculating the efficiency from the Run 9 dijet embedding sample using the following algorithm:
Update 02.28.2018 -- Nfit Cut Check
This is a brief check of how the cut on the no. of hits fit affects the pp recoil jet distribution. I apply a cut of Nfit >= 15 on all tracks used in the jet finding process.
Update 02.27.2018 -- 'IdTruth' and Etc. vs. Momentum
Below are some plots which show how the global dca, 'idTruth' (the index of the MC track which the detector track was matched to), 'qaTruth' (the percentage of hits successfully matched to an MC track
Update 02.26.2018 -- Average Trigger Et
To make sure we're comparing apples-to-apples when comparing our pp (and Pythia) results to our AuAu results, I've plotted the trigger Et distributions for both pi0 and gamma-rich triggers in data and
Update 02.26.2018 -- Run 9 Embedding: Bad Phi Region
Previously in the comparison of charged hadron triggers in the Run 9 dijet embedding to the pi0 triggers in Run 9 data, the embedding showed a systematic depletion of tracks in the trigger pT range (9
Update 02.23.2018 -- Run 9 pp Efficiency: Efficiency Using 'idTruth'
This is a follow-up to yesterday's post:
Update 02.22.2018 -- Run 9 pp Efficiency: Using StMuMcTracks
The shape of the track efficiency (as a function of pT) looked odd when I calculated it from the Run 9 dijet embedding sample (see the blog post below). I calculated it using all detector and pa
