Abstract

We consider supersymmetric grand unified theories with soft supersymmetry-breaking scalar masses [Formula: see text] specified above the GUT scale (super-GUTs) and patterns of Yukawa couplings motivated by upper limits on flavour-changing interactions beyond the Standard Model. If the scalar masses are smaller than the gaugino masses [Formula: see text], as is expected in no-scale models, the dominant effects of renormalisation between the input scale and the GUT scale are generally expected to be those due to the gauge couplings, which are proportional to [Formula: see text] and generation independent. In this case, the input scalar masses [Formula: see text] may violate flavour maximally, a scenario we call MaxSFV, and there is no supersymmetric flavour problem. We illustrate this possibility within various specific super-GUT scenarios that are deformations of no-scale gravity.

摘要

我们考虑具有在大统一理论(GUT)尺度之上指定的软超对称破缺标量质量[公式:见正文]的超对称大统一理论(超 GUT),以及由超出标准模型的味变相互作用的上限所激发的汤川耦合模式。如果标量质量小于规范玻色子质量[公式:见正文],正如在无标度模型中所预期的那样,通常预计在输入尺度和 GUT 尺度之间重整化的主要效应是由规范耦合引起的,规范耦合与[公式:见正文]成比例且与代无关。在这种情况下,输入标量质量[公式:见正文]可能最大程度地违反味对称性,我们将这种情形称为最大味违反(MaxSFV),并且不存在超对称味问题。我们在作为无标度引力变形的各种特定超 GUT 情形中说明了这种可能性。
