摘要
In the analysis of Beijing Spectrometer (BES) data, the dE/dx and TOF information have been used in the particle identification. When combining the dE/dx and TOF information to do the particle identification, the chi(2) of dE/dx and TOF are usually added with equal weight. But the particle identification capability of dE/dx and TOF is different in different momentum region. In this paper, we give the weights of dE/dx and TOF in different momentum region and form a new variable which uses different weights for dE/dx and TOF informations to do the particle identification.
