Kahler G2-MSSM的独立性
Kahler Independence of the G2-MSSM
摘要：
G2-MSSM是一个耦合到模场的粒子物理模型，具有有趣的现象学，可用于对撞机和天体物理实验。在本文中，我们考虑一个更一般的模型，其模Kahler势是一个完全任意的G2-完整Kahler势，其物质Kahler势也是更一般的。我们证明了BSM粒子的真空结构和光谱在这类更一般的理论中基本不变。特别是，相对于引力子质量和模质量，高更质量仍然被抑制。我们还考虑了高阶修正对物质Kahler势的影响，并发现LSP的性质与风味效应之间存在联系。
英文摘要：
The G2-MSSM is a model of particle physics coupled to moduli fields with interesting phenomenology both for colliders and astrophysical experiments. In this paper we consider a more general model - whose moduli Kahler potential is a completely arbitrary G2-holonomy Kahler potential and whose matter Kahler potential is also more general. We prove that the vacuum structure and spectrum of BSM particles is largely unchanged in this much more general class of theories. In particular, gaugino masses are still supressed relative to the gravitino mass and moduli masses. We also consider the effects of higher order corrections to the matter Kahler potential and find a connection between the nature of the LSP and flavor effects.
