通过逐事件2 π玻色-爱因斯坦关联探测源的不均匀性

Detection of source inhomogeneity through event-by-event two-pion Bose-Einstein correlations

Yan-Yu Ren, Wei-Ning Zhang, Jian-Li Liu

摘要:

本文发展了一种通过两π玻色-爱因斯坦关联来探测超相对论重离子碰撞中π介子发射源不均匀性的方法。单粒子和混合粒子的两π关联函数之间的误差反加权涨落的均方根是探测的有用观测量。通过研究不同碰撞参量区域的加权涨落的均方根值,人们有望确定即将到来的大型强子对撞机(LHC)重离子实验中粒子发射的不均匀性。

英文摘要:

We develop a method for detecting the inhomogeneity of the pion-emitting sources produced in ultra-relativistic heavy ion collisions, through event-by-event two-pion Bose-Einstein correlations. The root-mean-square of the error-inverse-weighted fluctuations between the two-pion correlation functions of single and mixed events are useful observables for the detection. By investigating the root-mean-square of the weighted fluctuations for different impact parameter regions people may hopefully determine the inhomogeneity of the particle-emitting in the coming Large Hadron Collider (LHC) heavy ion experiments.
