标题： Some Comments on the `Quirks' Scenario

摘要： 我们讨论具有长寿命或稳定带色粒子的模型的各种方面。 特别是我们关注一个理想的Quirk模型，其中包含电弱中性重粒子（约TeV量级），这些粒子携带普通色和另一种非常低能标$\Lambda'$的$ SU'(3)$色。 我们表明，与人们的直觉相反，这样的模型在宇宙学上是一致的，并且即使对于非常低的O(10 eV)$\Lambda'$也能避免许多“陷阱”，而无需假设低温再加热温度。 我们还表明，由海洋水中包含在重同位素中的宇宙射线产生的Quirks的预期产量与后者极为严格的限制是一致的。 这避免了对Quirk模型的真实威胁，这种威胁无论宇宙学如何都会将其排除。 最后我们简要评论了可能的LHC信号。 显示英文摘要

摘要： We discuss various aspects of models with long-lived or stable colored particles. In particular we focus on an ideal Quirk model with electroweak neutral heavy (O(TeV)) particles which carry ordinary color and another $ SU'(3)$ color with a very low scale $\Lambda'$. We show that contrary to what one might think, such a model is cosmologically consistent and evades many "Pitfalls" even for very low O(10 eV) $\Lambda'$ and without assuming a low reheat temperature. We also show that the expected production of Quirks by cosmic rays which are incorporated in heavy Isotopes in Ocean water is consistent with the highly stringent bounds on the latter. This evades a real threat to the Quirk model which would have excluded it regardless of Cosmology. Finally we briefly comment on possible LHC signatures.
