玻色-爱因斯坦关联中的两个尺度
Two scales in Bose-Einstein correlations
摘要：
我们认为高能强子碰撞中产生的次级辐射是由分布在相互作用振幅所占据的碰撞参量空间中更大面积上的小尺寸源发射的。也就是说，两个发射的全同粒子的玻色-爱因斯坦关联应该用一个“双半径”参数化模型来描述。我们讨论了预期的能量，充电的多重性和横向动量对（即，$\sqrt{s},~N_{\rm ch}, k_t$）的小尺寸和大尺寸组件的行为。
英文摘要：
We argue that the secondaries produced in high energy hadron collisions are emitted by small size sources distributed over a much larger area in impact parameter space occupied by the interaction amplitude. That is, Bose-Einstein correlation of two emitted identical particles should be described by a `two-radii' parametrization ansatz. We discuss the expected energy, charged multiplicity and transverse momentum of the pair (that is, $\sqrt{s},~N_{\rm ch}, k_t$) behaviour of both the small and large size components.
