能量缺失衰变链质量的精确确定

Accurate Mass Determinations in Decay Chains with Missing Energy

Hsin-Chia Cheng, Dalit Engelhardt, John F. Gunion, Zhenyu Han, Bob McElrath

摘要:

许多超越标准模型的理论包括一个稳定的暗物质候选者,它在对撞机探测器中产生丢失/不可见的能量。如果在大型强子对撞机上观察到,我们必须确定它的质量和其他属性(以及它的伙伴)是否预测了正确的暗物质遗迹密度。给出了一种新的测定其质量的方法,误差很小。

英文摘要:

Many beyond the Standard Model theories include a stable dark matter candidate that yields missing / invisible energy in collider detectors. If observed at the Large Hadron Collider, we must determine if its mass and other properties (and those of its partners) predict the correct dark matter relic density. We give a new procedure for determining its mass with small error.
