论文摘要
我们研究了赫尔的异国情调超弦理论的弦线学问题，并多次使用欧几里得字符串/麸皮和多次。已知这些被幽灵发生的病理困扰。另一方面，这些理论展示了Sitter解决方案。我们的特别重点在于这种保姆解决方案和无鬼brane世界的共存问题。为此，欧几里得基本字符串的世界表CFT描述被普遍化，还包括开放式弦乐/d-Brane部门。要求在“可观察”轨距理论部门本身是非骨料的，因此发现了DS Swampland猜想的概括。
We investigate string-phenomenological questions of Hull's exotic superstring theories with Euclidean strings/branes and multiple times. These are known to be plagued by pathologies like the occurrence of ghosts. On the other hand, these theories exhibit de Sitter solutions. Our special focus lies on the question of the coexistence of such de Sitter solutions and ghost-free brane worlds. To this end, the world-sheet CFT description of Euclidean fundamental strings is generalized to include also the open string/D-brane sector. Demanding that in the "observable" gauge theory sector the gauge fields themselves are non-ghosts, a generalization of the dS swampland conjecture is found.
