DEVELOPMENT AND APPLICATION OF THE FAST MONTE-CARLO SIMULATION METHODFOR BEIJING TAU-CHARM FACTORY (BTCF)

Based on the existing concept design and the expected performance of t he detector at the future tau-charm factory, a fast Monte Carlo simula tion program using the BES software frame and its data structure has b een developed. Various important and/or interesting physics issues hav e been simulated using this method and a series of important physics r esults have been attained. The design idea, the program frame, and the advantages of this method have been described. This method can greatl y save CPU and disk space and is specially suitable for BES users. The physics results obtained from the simulation demonstrate the physics importance of building the BTCF.
