TOF Efficiency

In order to estimate the efficiency of the TOF charged tracks are used that hit the TOF wall. For such tracks the closed TOF point to the track point is obtained and the distance to this point is recorded as a function of track momentum an in bins of 9cm x 9cm in x and y at the TOF wall. This is done for both DATA and MC:

  1. DATA(left) MC(right) TOF point match to tracks for bin 15/20:
    Below is shown the distribution of dr for track momenta larger than 1GeV/c

  2. For both DATA and MC the track hit location is binned in 9x9 cm
    Bin 15/20 (x/y) in x and y and shown in the following 2d plots(data/mc):
    The distance of the point tof point from the track hit position vs track momentum.
