论文摘要
事先提出的观察方法使用事件混合技术用于玻色网相关性（BEC）的测量值（BEC）的测量值非常低，由于样本还原和引入了额外和不必要的拟合参数，因此仍然不令人满意。我们在这里提出了一种新的混合切割，命名为能量总和范围（ESR）切割的事件混合方法，以研究两杆玻色 - 因斯坦相关性（BEC），在三个最终状态颗粒中仅有两个相同pions的反应中。这种混合方法采用两杆能量和特征来控制混合程序，而无需消除任何原始事件。进行数值模拟以显示这种新的BEC观察方法的生存能力。
Prior proposed observing approaches using event mixing technique for Bose-Einstein correlations (BEC) measurements in exclusive reactions with very low multiplicities are still unsatisfactory due to the problems of sample reduction and introducing extra and unnecessary fitting parameters. We here propose an event mixing method with a new mixing cut, named energy sum range (ESR) cut, to investigate two-pion Bose-Einstein correlations (BEC) in reactions with only two identical pions among three final state particles. This mixing method employs two-pion energy sum characteristic to control the mixing procedures, with no requirement on eliminating any original events. Numerical simulations are performed to show the viability of this new BEC observing method.
