摘要：

We examine the decay width of Z → neutral invisibles in the supersymmetric flipped SU (5) model. It is found that these processes would give contributions to the Z width leading to the inference of a non-integer number of generations between close to three and ∼ 3.5, and we argue that an accurate determination of this quantity could lead to significant restrictions on the allowable parameter space in this model. © 1990.
