摘要
U(1)(X) SSM is a non-universal Abelian extension of the Minimal Supersymmetric Standard Model and its local gauge group is extended to SU(3)(C) x SU(2)(L) x U(1)(Y) x U(1)(X) . Based on the latest data of neutral meson mixing and experimental limitations, we investigate the process of B-0- B-0 over bar mixing in U(1)(X )SSM. Using the effective Hamiltonian method, the Wilson coefficients and mass difference Delta m(B )are derived. The abundant numerical results verify that v S , M-D(2) , lambda(C) , mu , M-2 , tan(beta) , g(YX) , M-1 and lambda(H) are sensitive parameters to the process of B-0- B-0 over bar mixing. With further measurement in the experiment, the parameter space of the U(1)(X) SSM will be further constrained during the mixing process of B-0- B(0 )over bar .
