我们开发了一种事件混合技术来观察非微扰 QCD 能量区域中光诱导反应中产生的两个相同中性介子之间的玻色-爱因斯坦相关性 (BEC)。研究发现，缺失质量一致性截断和π介子能量截断对于事件混合方法有效提取BEC可观测量至关重要。使用蒙特卡罗 (MC) 模拟来验证这些约束并确认该方法的效率。我们的工作为在较低能量下进行类似的 BEC 研究铺平了道路，其中发射的玻色子的多样性受到限制。
We have developed an event mixing technique to observe Bose-Einstein correlations (BEC) between two identical neutral pions produced in photo-induced reactions in the non-perturbative QCD energy region. It is found that the missing-mass consistency cut and the pion-energy cut are essential for the event mixing method to effectively extract BEC observables. A Monte Carlo (MC) simulation is used to validate these constraints and confirms the efficiency of this method. Our work paves the way for similar BEC studies at lower energies where the multiplicity of emitted bosons is limited.
