The main consideration in constructing a successor to the Standard Model has long been the problem of stability (naturalness) of the electroweak scale, giving rise to the supersymmetry and composite Higgs paradigms. While the non-observation (so far) of the expected new particles is puzzling, there is increasingly compelling indirect evidence for new particles in the 1-10 TeV range in a number of precision, flavour-physics measurements, of a kind that is not generically expected in the standard paradigms. The aim of this project is to construct viable theoretical mechanisms that give rise to the observed effects, while addressing the naturalness problem and the absence of the signals usually associated with it, and explore possible connections with other phenomena (e.g., dark matter and evolution of the early universe).

长期以来，在构建标准模型的后继者时，主要考虑的是电弱尺度的稳定性（自然性）问题，这导致了超对称性和复合希格斯范式的出现。虽然（到目前为止）没有观测到预期的新粒子令人困惑，但在一些精确的味道物理测量中，越来越多的令人信服的间接证据表明新粒子在1-10 TeV范围内，这是一种在标准范式中通常不期望的。该项目的目的是构建可行的理论机制，引起观察到的效果，同时解决自然性问题和通常与之相关的信号的缺乏，并探索与其他现象的可能联系（例如，暗物质和早期宇宙的演化）。
