The phenomenology study of dark matter in MSSM
LI Dongwei
Abstract：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.
