400GeV/c pp碰撞类环事例的产生

Production of Ring-like Events in pp Collisions at 400GeV / c

利用400GeV／cpp碰撞产生的带电粒子赝快度分布的实验数据，研究了类环事例的产生机制．结果表明在一有限的时间-空间范围内相干胶子辐射是类环事例的一种可能的产生机制，但肯定不是主要的．

The production mechanism of ring-like events has been investigated by using the data of pseudorapidity distribution of charged particles produced in pp collisions at 400GeV/c. The results show that the model of coherent gluon emission within a finite region of space-time is a possible production mechanism of ring-like events, but certainly not dominant.
