Summary
- DC dE/dx determination is done and checked into svn. Confidence levels are flat for protons, pions, and kaons, in both the FDC and CDC.
K+'s
- FDC K+ dE/dx μ & σ
- σ is dependent on amount of information: # hits USED (= 1/2 of total # hits: reject largest dE/dx hits to remove Landau tail)
- CDC K+ dE/dx μ & σ
- σ is dependent on amount of information: # hits USED (= 1/2 of total # hits: reject largest dE/dx hits to remove Landau tail)
Particle Overlay
- dE/dx μ vs p for different particle types & CDC/FDC (error bar is overall σ (particles generated uniformly across θ & p))
- 2nd plot is zoomed in version of 1st plot
- Low momentum kaons overlap pions because they decayed: dE/dx χ2 not evaluated for kaons in this region.
Confidence Levels
- Confidence Levels for FDC/CDC dE/dx for protons, pions, and kaons:
