对“怪癖”情景的一些评论
Some Comments on the `Quirks' Scenario
摘要：
我们讨论了长寿命或稳定的有色粒子模型的各个方面。特别是，我们专注于一个理想的夸克模型与电弱中性重（O（TeV））粒子进行普通的颜色和另一个$ SU'(3)$颜色与一个非常低的规模$Λ'$。我们发现，与人们可能认为的相反，这样的模型是宇宙学上一致的，即使对于非常低的O（10 eV）$Λ'$和不假设低的再热温度，也避免了许多“陷阱”。我们还表明，预期的生产夸克的宇宙射线，这是纳入重同位素在海水中是一致的，后者的高度严格的界限。这就避免了对夸克模型的真正威胁，而夸克模型本来会排除它，不管宇宙学如何。最后，我们简要评论可能的LHC签名。
英文摘要：
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 $Λ'$. 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) $Λ'$ 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.
