论文摘要
我们表明，QCD的基本或更高维表示中的矢量夸克可以通过手性对称性破坏冷凝物以现象学上可行的方式产生电力用量表。因此，生成的量表是通过数值求解dyson-schwinger方程来确定的，并且这些量表很可观，因为它们会随硬矢量样质量而生长。通过共同不变的标量扇形将这样的量表传达给标准模型，可以动态生成电脉冲尺度而没有自然性问题，因为所有非动力学质量尺度均受到手性对称性的保护。我们提出了一个最小的设置，该设置仅需要一个新的中性标量，其质量不超过电脉冲尺度，并且在（多）TEV量表上都需要类似矢量的夸克。两者都与当前的界限一致，并且对于LHC和未来山脉的未来实验搜索都有吸引力。根据矢量般的夸克的超额费用，由它们制成的黑质是有色的结合状态，这将是有趣的暗物质候选者。
We show that vector-like quarks in the fundamental or higher-dimensional representations of QCD can generate the electro-weak scale in a phenomenologically viable way by chiral symmetry breaking condensates. The thereby generated scales are determined by numerically solving the Dyson-Schwinger equation and these scales are sizable, because they grow with the hard vector-like mass. Communicating such a scale to the Standard Model via a conformally invariant scalar sector can dynamically generate the electro-weak scale without a naturalness problem, because all non-dynamical mass scales are protected by chiral symmetry. We present a minimal setup which requires only a new neutral scalar with mass not too far above the electro-weak scale, as well as vector-like quarks at the (multi-)TeV scale. Both are consistent with current bounds and are attractive for future experimental searches at the LHC and future colliders. Depending on the hypercharge of the vector-like quarks, hadrons made of them are color-neutral bound states which would be interesting Dark Matter candidates.
