Mathusla探测器是一个简单的大体积跟踪探测器，位于大型强子对撞机的一个通用实验的上方。该检测器在[J. P. Chou，D.科廷和H. Lubatti，Phys. Lett. B 767，29（2017）PYLBAJ 0370 -269310.1016/j.physletb.2017.01.043]，以检测可能在高能质子-质子碰撞中产生的奇异、中性、长寿命粒子。在本文中，我们考虑使用有限的信息，Mathulsa将提供的衰变产物的长寿命粒子。对于在希格斯玻色子衰变的情况下，长寿命的粒子是成对产生的，我们表明，它是可能的，以测量该粒子的质量，并确定占主导地位的衰变模式与不到100个观察到的事件。我们讨论了Mathusla区分长寿命粒子的产生模式以及在更一般的情况下确定其质量和自旋的能力。
The MATHUSLA detector is a simple large-volume tracking detector to be located on the surface above one of the general-purpose experiments at the Large Hadron Collider. This detector was proposed in [J. P. Chou, D. Curtin, and H. J. Lubatti, Phys. Lett. B 767, 29 (2017)PYLBAJ0370-269310.1016/j.physletb.2017.01.043] to detect exotic, neutral, long-lived particles that might be produced in high-energy proton-proton collisions. In this paper, we consider the use of the limited information that MATHULSA would provide on the decay products of the long-lived particle. For the case in which the long-lived particle is pair-produced in Higgs boson decays, we show that it is possible to measure the mass of this particle and determine the dominant decay mode with less than 100 observed events. We discuss the ability of MATHUSLA to distinguish the production mode of the long-lived particle and to determine its mass and spin in more general cases.
