| 摘 要： | 用蒙特卡罗方法模拟e+e-碰撞,研究了在91.2Gev质心能量产生的双喷注事件的动力学起伏随截断参量ycutt的变化情况.结论是:(1)喷注内部的动力学起伏的各向异性随着截断参数ycut的变化而显著地改变;(2)存在一个转变点,在该点处动力学起伏在纵一横平面是各向同性的,而在横平面是各向异性的.

| Abstract: | A Monte Carlo study o f the dynamical fluctuations for the two-jets events in e + e - collisions at 91.2 Gev has been carried out.The results as fellow:(1)The anisotropy of dynamical fluctuations inside jets changed evidently with the cut parameter y cut ;(2)A transition points existed,where the dynamical fluctuations were anisotropic in the longitudinal-transverse planes and istropic in the transvers plane. |
