本文研究了由三个右手中微子扩展的最小超对称标准模型。假设中微子的质量是纯粹的狄拉克型，最轻的右手中微子R可以是最轻的超粒子（LSP）。我们讨论了LSP-R成为宇宙暗物质的可能性，特别关注了早期宇宙中R的产生。这项工作是基于与K. Ishiwata和T. Moroi [1，2].
We consider the minimal supersymmetric standard model (MSSM) extended by three right-handed neutrinos. Assuming that neutrino masses are purely Dirac-type, the lightest right-handed sneutrino R can be the lightest superparticle (LSP). We discuss the possibility that the LSP R becomes dark matter of the universe, paying attention to the production of R in the early universe. This work is based on collaboration with K. Ishiwata and T. Moroi [1, 2].
