关于长程玻色-爱因斯坦关联--包括对OPAL，L3和CMS玻色-爱因斯坦关联的分析
On long-range pionic Bose-Einstein correlations -- Including analyses of OPAL, L3 and CMS BECs
摘要：
长程关联在分析玻色-爱因斯坦关联中起着重要的作用。在许多情况下，这种相关性是现象学上引入的。在这项研究中，我们提出了一个分析形式。利用该公式和$τ$ -模型，我们分析了OPAL BEC和L3 BEC在$Z^0$ -极和CMS BEC在0.9和7 TeV.这两种方法估计的参数是一致的。利用四维欧氏空间中的傅里叶变换，我们还研究了一些π介子对的密度分布。
英文摘要：
Long-range correlation plays an important role in analyses of pionic Bose-Einstein correlations (BECs). In many cases, such correlations are phenomenologically introduced. In this investigation, we propose an analytic form. By making use of the form, we analyze the OPAL BEC and the L3 BEC at $Z^0$-pole and the CMS BEC at 0.9 and 7 TeV using our formulas and the $τ$-model. The parameters estimated by both approaches are found to be consistent. Utilizing the Fourier transform in four-dimensional Euclidean space, a number of pion-pair density distributions are also studied.
