摘要
对sqr(s)=540Gev能量下的高能强子-强子碰撞得到的单事件平均横动量p。对多重数N的散点图进行了仔细分析后指出;其中大多重数、大事件是碰撞过程中出现硬分量的又一个实验证据,并用仅含软分量的单分量模型和既含软分量又含硬分量的二分量模型的MonteCarlo模拟定性地证实了这一论断。
After carefully analysing the scatter plot of pt vs. N of hadron-hadron collisions at 540GeV, we point out that the appearence of large average transverse momentum per event p t and large multiplicity N is a new experimental evidence of existing hard component at the collision. The Monte Carlo simulation for one (soft) and two (both hard and soft) component model demonstrates qualitatively correct ness of this arguement.
