最小超对称模型的理论自然性随着LUX-ZEPLIN实验数据的更新而渐趋恶化。在预测Z玻色子质量和暗物质残留密度方面，模型均面临严重的精细调节。特别是在暗物质利用Higgs或Z玻色子介导共振湮灭从而获得正确的残留密度时，问题尤为明显。
Abstract：The theoretical naturalness of the Minimal Supersymmetric Standard Model( MSSM) has been increasingly challenged by the updated data from the LUX-ZEPLIN( LZ) experiment. The model now faces severe fine-tuning problems in predicting both the Z boson mass and the dark matter relic density,which becomes particularly pronounced when dark matter relies on Higgs-or Z-mediated resonant annihilation to achieve the correct relic density.
