Based on the perturbative QCD predictions of gluonic distributions and branch cross section of the J/(?) decay via hadronic, electromagnetic,and radiative channels, the strict solutions of LUND area law of string fragmentation had-ronization are used to treat nonperturbative hadronic production processes, a possible description and Monte Carlo packet for the J/(?) hadronic decay are obtained.
基于微扰QCD所预言的J/ψ衰变道胶子分布及其分支截面和LUND弦碎裂模型强子化面积定律的严格解,得到J/ψ所有衰变模式的微扰和非微扰过程的一种可能的描述,相应的Monte Carlo产生器LUARLW所作的初步模拟结果与BES获取的J/ψ数据的多种带电粒子谱分布和事例形状拓扑分布符合较好。
In the teaching of central field, we should pay attention to turning the relative motion of two - body into one dimentuonal radial motion by introducing two physical concepts of reduced mass and effective potential energy, and we should also pay attention that the area law is the geometrical description of the conservation of angular momentum in the central field.
