针对LZ事件非弹性双重态解释受太阳俘获约束的问题，提出环境依赖质量劈裂机制，通过超轻标量密度诱导增强太阳内劈裂以抑制俘获，虽现象学可行但需严重精细调节。
AI中文摘要：
LUX-ZEPLIN实验报告的248 keV反冲能量事件的非弹性电弱双重态解释面临来自太阳俘获的强约束。我们提出一种由与电子二次耦合的超轻标量产生的环境依赖质量劈裂。其密度诱导的期望值增强了太阳中的劈裂，同时保持实验室值不变，提供了一种抑制太阳俘获的机制。我们推导了该机制的条件，并检验了来自恒星冷却和电子质量变化的约束。我们发现该情景在现象学上是可行的，但标量势存在严重的精细调节问题。
英文摘要：
The inelastic electroweak-doublet interpretation of the $248\,{\rm keV}$ recoil energy event reported by LUX-ZEPLIN faces strong constraints from solar capture. We propose an environment-dependent mass splitting generated by an ultralight scalar coupled quadratically to electrons. Its density-induced expectation value enhances the splitting in the Sun while preserving the laboratory value, providing a mechanism to suppress solar capture. We derive conditions for this mechanism and examine constraints from stellar cooling and electron-mass variations. We find that this scenario is phenomenologically viable, while it suffers from severe fine-tuning of the scalar potential.
