Navigating the Landscape of Compactified String Theory with Experimental Data.

[摘要] This thesis discusses the methodology for extracting concrete experimental predictions from compactified string theories. The primary difficulty encountered in phenomenological studies of string theory is the presence of a ``string landscape;;, which refers to the numerous physically inequivalent ground states (vacuaa) predicted by a particular string compactification. Without a mechanism for selecting the ``true;; vacuum that describes nature, it is difficult to make predictions for low energy physics purely from UV considerations. In this thesis, we will instead leverage experimental constraints to isolate regions of the string landscape that are consistent with all known experimental data. Given these restrictions on the string landscape, it is possible to make concrete predictions for upcoming experiments. We will carry out this procedure, and study the resulting phenomenology for collider physics and dark matter predicted by realistic compactified string theories. We will also discuss how these predictions can be tested with new experiments, such as a future hadron collider operating at 100 TeV. Some parts of this work (Chapters 2 and 3) are specific to a particular string compactification known as the ``G2-MSSM;;, while other parts (Chapters 4 and 5) are applicable to string compactifications in general.
