Light neutralino dark matter in U(1)XSSM
The U(1)X extension of the minimal supersymmetric standard model (MSSM) is called as U(1)XSSM with the local gauge group SU(3)C×SU(2)L×U(1)Y×U(1)X. U(1)XSSM has three singlet Higgs superfields beyond MSSM. In U(1)XSSM, the mass matrix of neutralino is 8×8, whose lightest mass eigenstate possesses co...
