目前的对撞机数据对任何类型的新的强相互作用粒子与希格斯玻色子的耦合都有严格的限制。我们分析了非三重态SU（3）C表象奇异夸克的唯象极限及其对Higgs搜索的意义。在实验允许的质量范围内，标准模型希格斯粒子的发现排除了与之耦合的奇异夸克的存在。因此，这样的QCD粒子只能存在，前提是它们的质量不来源于SM希格斯机制。
The present collider data put severe constraints on any type of new strongly-interacting particle coupling to the Higgs boson. We analyze the phenomenological limits on exotic quarks belonging to non-triplet SU(3)_C representations and their implications on Higgs searches. The discovery of the Standard Model Higgs, in the experimentally allowed mass range, would exclude the presence of exotic quarks coupling to it. Thus, such QCD particles could only exist provided that their masses do not originate in the SM Higgs mechanism.
