摘　　要：LUX-ZEPLIN暗物质探测实验的最新数据,显著影响到最小超对称模型中的暗物质物理的唯象学性质.以Wino组分为主的暗物质已经被完全排除.以Higgsino为主要组分的暗物质的存活参数空间被严重压缩.以Bino为主要组分的暗物质暂无被排除风险,但是理论在预言Z玻色子质量时至少需要引入3.1%的精细调节.随着LUX-ZEPLIN实验数据的持续更新,最小超对称模型可行参数空间将进一步收窄,模型面临的自然性问题也将愈发明显.The latest LUX-ZEPLIN experimental data of the dark matter detection has significantly affected the phenomenological properties of dark matter physics in the MSSM.The Wino-like dark matter has been completely excluded.The viable parameter space of Higgsino-like dark matter has been severely compressed.The Bino-like dark matter has no risk of being excluded,but the theory needs at least 3.1%fine-tuning when predicting the mass of the Z boson.With the update of the LUX-ZEPLIN experimental data,the viable parameter space of the MSSM will be further narrowed,and the naturalness problem will also become more obvious.
