我们采用最小粒子含量原理和最一般的可重整化拉格朗日原理，构造了一个新的最小标准模型，它融合了最小标准模型(MSM)之外的物理新发现：暗能量、非重子暗物质、中微子质量，以及重子不对称性和宇宙暴胀。我们的模型纯粹是基于经验事实，而不是美学。除了MSM，我们只需要六个新的自由度。它没有过多的味道变化效应、CP破坏、太快的质子衰变、电弱精度数据的问题，以及不想要的宇宙遗迹。任何超越MSM的物理学模型都应该与这个模型在现象学上的成功进行比较。
We construct the new Minimal Standard Model that incorporates the new discoveries of physics beyond the Minimal Standard Model (MSM): dark energy, non-baryonic dark matter, neutrino masses, as well as baryon asymmetry and cosmic inflation, adopting the principle of minimal particle content and the most general renormalizable Lagrangian. We base the model purely on empirical facts rather than aesthetics. We need only six new degrees of freedom beyond the MSM. It is free from excessive flavor-changing effects, CP violation, too-rapid proton decay, problems with electroweak precision data, and unwanted cosmological relics. Any model of physics beyond the MSM should be measured against the phenomenological success of this model.
