论文摘要
在我们的世界中，粒子物理的标准模型包含在其中的相当棘手的理论，称为QCD。经常将具有两种颜色的玩具版本作为模型限制和手性对称性破坏场理论。在这里，如果我们在标准模型中进行这种变化，我们将研究各个距离尺度上的变化级联。有可能限制在Hadronic量表上的变化。但是，实际上发生的小变化实际上降至远红外，核和原子物理学以及化学。通过此，它也可能影响恒星和星系的演变。我们评论宇宙对物理学在夸克的规模上的敏感性。
In our world the standard model of particle physics contains within it the fairly intractable theory called QCD. A toy version with two colours is often studied as a model confining and chiral symmetry breaking field theory. Here we investigate the cascade of changes at various distance scales if we make this change within the standard model. It is possible to limit the changes at the hadronic scale. However, the minor changes that occur actually cascade down to the far infrared, into nuclear and atomic physics, and chemistry. Through this it also possibly affects the evolution of stars and galaxies. We remark on this unexpected sensitivity of the universe to physics at the scale of quarks.
