半不可见衰变中的运动学观测量

Kinematical Observables in Semi-Invisible Decays

Kai Ma

摘要:

在对撞机上研究物理学时,看不见的粒子经常以最终状态出现。在测量丢失的能量时,实验精度也很低。在本文中,我们提出了一种研究涉及不可见粒子的过程的一般方法。我们提供了两个运动学观测值,这是敏感的生产运动学在不同的地区,因此是互补的。我们的方法的使用说明了三个例子。结果表明,在S/B显著性较低的情况下,我们的观测量仍然是有用的。

英文摘要:

Invisible particles frequently appear in final state in studying physics at colliders. Experimental precision is also low in measuring missing energy. In this paper, we propose a general approach for studying process involving invisible particles. We provided two kinematical observables which are sensitive to production kinematics in different regions, and hence are complementary. Usage of our approach is illustrated by three examples. It is shown that our observables are still useful in case of that the significance S/B is relatively low.
