【Abstract】 The well known Monte Carlo simulation package JETSET is developed to simulate the hadronic final states in e +e - collision with center of mass energy E cm 10GeV,but not suitable for few GeV energy region. We develop a Monte Carlo program, LUARLW,which can well simulate two body up to six body hadronic final states at BEPC energy region. In LUARLW,the effects of all gluonic emissions are neglected. The LUARLW produces more than 14 distributions,which agree with the BES data very well. This package is used for estimating hadronic events detection efficiencies in the measurements of total cross section of hadron production at BES between 2\₅ GeV.更多还原
