Plots - Dca Distributions


The Following are the results for dca distributions for different pT bins in Pi Minus. The results of dca agrees reasonable for the cut-off of 2 cm and above. These plots were done using the macro plot_dca.C

Event Selection Criteria

    * Production: P06ib
    * Vertex restriction: |x|<3.5cm, |y|<3.5cm, |z|<25.0cm
    * N Fit points >= 25
    * DCA < 3 cm
