在对撞机实验中用碰撞参量重建τ轻子

Tau lepton reconstruction at collider experiments using impact parameters

Daniel Jeans

摘要:

我们提出了一种新的方法来重建对撞机实验中包含强子衰变τ轻子对的事件。这种方法依赖于对tau产生顶点的准确了解和对其带电衰变产物的精确测量。该方法不需要对τ对的质心或不变质量做任何假设,并且对沿光束方向的动量损失不敏感。我们使用在ILD检测器中完全模拟的e+e-> mu+ mu- tau+ tau-事件来演示该方法。

英文摘要:

We present a novel method for the reconstruction of events containing pairs of hadronically decaying tau leptons at collider experiments. This method relies on accurate knowledge of the tau production vertex and precise measurement of its charged decay products. The method makes no assumptions about the centre-of-mass or invariant mass of the tau pair, and is insensitive to momentum loss along the beam direction. We demonstrate the method using e+e- -> mu+ mu- tau+ tau- events fully simulated in the ILD detector.
