摘要：

我们研究的微调问题的背景下，一般规范调解。对松弛微调的数值分析。我们分析的问题，在典型的三种情况下的信使规模，即，大统一组织（$2\times10^{16}$ GeV），中间（$10^{10}$ GeV），相对较低的能量（$10^6$ GeV）的规模。在每个信使标度中，发现了使调谐度降低约10%的参数空间，并且发现了胶子质量、维诺质量和软标量质量之间的某些比值是有利的。结果表明，随着信使尺度的降低，有利于调谐的区域变窄，信使尺度下的终止质量快子初始条件有利于缓解相对低能信使尺度下的微调问题.从$μ-B$问题的观点来看，我们的光谱也很重要。

英文摘要：

We study the fine-tuning problem in the context of general gauge mediation. Numerical analyses toward for relaxing fine-tuning are presented. We analyse the problem in typical three cases of the messenger scale, that is, GUT ($2\times10^{16}$ GeV), intermediate ($10^{10}$ GeV), and relatively low energy ($10^6$ GeV) scales. In each messenger scale, the parameter space reducing the degree of tuning as around 10% is found. Certain ratios among gluino mass, wino mass and soft scalar masses are favorable. It is shown that the favorable region becomes narrow as the messenger scale becomes lower, and tachyonic initial conditions of stop masses at the messenger scale are favored to relax the fine-tuning problem for the relatively low energy messenger scale. Our spectra would also be important from the viewpoint of the $μ-B$ problem.
