Study of neutral track measurement at BES II
- 1. Academia Sinica, Beijing (China). Inst. of High Energy Physics
Description
The measurement errors of the deposited energy and position of neutral tracks in Barrel Shower Counter (BSC) of BES II are investigated. The errors of energy and position of real data are determined by radiative Bhabha events, while the errors of Monte Carlo Data are determined by e+e-→γγ events. Then the corrections are tested by the selected ρπ sample, which shows better pull and Confidence Level distribution after the correction. The results are already applied to the kinematic fitting, which can improve the physics results at BES II
