论文摘要
我们表明，可以同时在克劳斯，纳斯里（Nasri）和Trodden提出的三环SEESAW模型中同时解释粒子物理和宇宙学中的三个开放性问题：中微子质量的起源，暗物质的身份以及宇宙Baryon不对称的起源。我们讨论了通过三个右中微子成功进行瘦素发生的困难，并提出了一个具有四个右中微子的场景，可以满足所有观察性约束。这种情况预测了一个类似于月光的粒子，如几百个GEV，可以通过未来的对撞机实验来探测。
We show that three open questions in particle physics and cosmology: the origin of neutrino mass, the identity of dark matter, and the origin of the baryon asymmetry of the universe can be explained simultaneously in the three-loop seesaw model proposed by Krauss, Nasri, and Trodden. We discuss the difficulty of successful leptogenesis with three right-handed neutrinos, and we propose a scenario with four right-handed neutrinos that satisfies all observational constraints. This scenario predicts a sleptonlike particle as light as a few hundreds GeV that can be probed by future collider experiments.
