论文摘要
最新的，尽管有几个良好的候选人，但仍未有一个经典的弦乐理论解决方案的示例。我们在这里考虑两个新发现的10D Suprgravity De Sitter Solutions，并详细分析了它们是否可以晋升为经典的弦乐背景。为此，我们确定要满足的五个要求，并开发必要的10D工具来测试解决方案。最终，尽管有积极的部分结果，但他们俩都无法同时验证所有要求。获得的明确值为情况提供了明确的说明，分析突出了各种微妙之处。我们最终讨论了与规模分离问题的关系。
Up-to-date, there is no known example of a classical de Sitter solution of string theory, despite several good candidates. We consider here two newly discovered 10d supergravity de Sitter solutions, and analyse in great detail whether they can be promoted to classical string backgrounds. To that end, we identify five requirements to be met, and develop the necessary 10d tools to test the solutions. Eventually, they both fail to verify simultaneously all requirements, in spite of positive partial results. The explicit values obtained offer a clear illustration of the situation, and the analysis highlights various subtleties. We finally discuss the relation to the problem of scale separation.
