摘要：

We consider models with a gauged U(1), to which is coupled a fermionic standard-model singlet. If 's close the Universe, a Lee-Weinberg calculation gives the four-fermion coupling G from the mass m. We can then calculate the germanium scattering cross section as a function of m. The results are nearly model independent and close to experimental limits for 10 GeVm 100 GeV. In the region 400 GeVm40 TeV the scattering cross section depends on MZ, and again approaches experimental limits if MZ2 TeV. © 1990 The American Physical Society.
