本文提出用氩实验检验LZ 248 keV反冲的两种解释：激发赝狄拉克态跃迁预言氩中336 keV谱线，而基态Higgsino被抬升则预言无氩事件，DEAP-3600数据可验证。

氩决定了LZ 248 keV反冲事件的性质。若将该事件解读为激发的赝狄拉克态跃迁至其基态，则该事件预言在氩中产生核反冲谱线，其能量为|\delta|\\,m_\chi/(m_\chi+m_{\rm Ar})，在200 GeV时对应336 keV，且该谱线强度是氙的十倍，两条谱线的位置可确定质量。若将该事件解读为被最快晕粒子抬升的基态Higgsino，则由于氩的阈值超过晕粒子的最大能量，预言氩中无事件。该比率仅依赖于运动学和形状因子，而DEAP-3600已记录的数据中预计包含数十个预期事件。
英文摘要
Argon decides what the LZ 248 keV recoil is. Read as an excited pseudo-Dirac state dropping to its ground state, the event predicts a nuclear-recoil line in argon at |δ|\,m_χ/(m_χ+m_{\rm Ar}), 336 keV at 200 GeV, at ten times the xenon rate, and the two line positions fix the mass. Read as a ground-state Higgsino lifted by the fastest halo particles, it predicts no argon events, since the argon threshold exceeds the halo maximum. The ratio depends only on kinematics and form factors, and the DEAP-3600 data already recorded hold tens of expected events.
