独立辐射源模型中的长程快度关联
Long-Range Rapidity Correlations in the Model with Independent Emitters
摘要：
在独立同辐射源模型的框架下，研究了两个独立快度窗口中多重数之间的关联，即长程关联。它表明，LRC系数，定义的缩放（相对）变量，然而，取决于前向快度窗口的绝对宽度，并不依赖于后向的宽度。LRC系数对前向快度接受度的依赖性仅用一个理论参数就能明确地找到。与ALICE 7TeV pp碰撞数据的初步比较表明，数据中的多重数LRC可以在建议的方法的框架内描述。
英文摘要：
The correlation between multiplicities in two separated rapidity windows, the so-called long-range correlation (LRC), is studied in the framework of the model with independent identical emitters. It's shown that the LRC coefficient, defined for the scaled (relative) variables, nevertheless depends on the absolute width of the forward rapidity window and does not depend on the width of the backward one. The dependence of the LRC coefficient on the forward rapidity acceptance is explicitly found with only one theoretical parameter. The preliminary comparison with ALICE 7TeV pp collisions data shows that the multiplicity LRC in the data can be described in the framework of the suggested approach.
