我们研究了对规介超对称破缺最小模型的各种修正。我们认为，在合理的假设下，信使行业的结构是相当有限的。我们研究了信使场和普通方克场和睡眠场可能混合的影响，特别是对普适性的违反。我们表明{mu}和B参数的可接受值可以自然地从离散的，可能是水平的对称中产生。我们声称，在超对称破缺参数A和B在树级别消失的模型中，tan{beta}可能在没有微调的情况下很大。我们解释了在这些模型中如何解决超对称CP问题。{版权所有}{ital 1997} {ital美国物理学会}
We study various modifications to the minimal models of gauge-mediated supersymmetry breaking. We argue that, under reasonable assumptions, the structure of the messenger sector is rather restricted. We investigate the effects of possible mixing between messenger and ordinary squark and slepton fields and, in particular, violation of universality. We show that acceptable values for the {mu} and B parameters can naturally arise from discrete, possibly horizontal, symmetries. We claim that in models where the supersymmetry-breaking parameters A and B vanish at the tree level, tan{beta} could be large without fine-tuning. We explain how the supersymmetric CP problem is solved in such models. {copyright} {ital 1997} {ital The American Physical Society}
