摘要:
所有观测双轻子对(例如 $e^+e^-$、$μ^+μ^-$)的实验都必须面对由非同一物理顶点的轨迹组合产生的组合本底问题。必须设计某种方法来计算并消除这种本底。在本文档中,我们描述了一种特定的事件混合方法,该方法依赖于 SeaQuest 谱仪和数据的许多独特方面。此处描述的方法以正确的归一化计算组合本底;即无需分配随后在后续拟合过程中确定的浮动归一化因子。我们应用了大量测试来证明该方法的可靠性。
英文摘要:
All experiments observing dilepton pairs (e.g. $e^+e^-$, $μ^+μ^-$) must confront the existence of a combinatoric background caused by the combining of tracks not arising from the same physics vertex. Some method must be devised to calculate and remove this background. In this document we describe a particular event-mixing method relying on many of the unique aspects of the SeaQuest spectrometer and data. The method described here calculates the combinatoric background with correct normalization; i.e., there is no need to assign a floating normalization factor that is then determined in a subsequent fitting procedure. Numerous tests are applied to demonstrate the reliability of the method.
