We analyse the sensitivity of quark flavour-changing observables to the MSSM, in a regime of heavy superpartners. We analyse four distinct and motivated frameworks characterising the structure of the soft-breaking terms by means of approximate flavour symmetries. We show that a set of six low-energy observables with realistic chances of improvement in the near future, namely , , , , and the phase of - mixing, could play a very important role in characterising these frameworks for superpartner masses up to TeV. We show that these observables remain very interesting even in a long-term perspective, i.e. even taking into account the direct mass reach of the most ambitious future high-energy colliders.
我们在重超伙伴的框架下分析了夸克味变可观测量对最小超对称标准模型（MSSM）的敏感性。我们通过近似味对称性分析了四个不同且合理的框架，这些框架刻画了软破缺项的结构。我们表明，一组在不久的将来有切实改进机会的六个低能可观测量，即 、 、 、 以及 - 混合相位，对于质量高达 TeV的超伙伴而言，在刻画这些框架方面可能发挥非常重要的作用。我们表明，即使从长期角度来看，即便是考虑到未来最雄心勃勃的高能对撞机的直接质量探测范围，这些可观测量仍然非常有趣。
