英文摘要 | The Monte-Carlo samples of pion, kaon and proton generated from 0.3 GeV/c to 1.2 GeV/c by the 'tester' generator from SIMBES which are used to simulate the detector of BES II are identified with the Bayesian neural networks (BNN). The pion identification and misidentification efficiencies are obviously better at high momentum region using BNN than the methods of chi(2) analysis of dE/dX and TOF information. The kaon identification and misidentification efficiencies are obviously better from 0.3 GeV/c to 1.2 GeV/c using BNN than the methods of chi(2) analysis. The proton identification and misidentification efficiencies using BNN axe basically consistent with the ones of chi(2) analysis. The anti-proton identification and misidentification efficiencies are better below 0.6 GeV/c using BNN than the methods of chi(2) analysis. |
