项目摘要

Investigations in theoretical high energy physics in areas of supersymmetry phenomenology, CP violation, dark matter and extra dimensions and their applications to model building will be carried out. The implications of the data from the Brookhaven g-2 experiment and of RUNII of the Tevatron for supersymmetry and surperstring theory will be explored. Correlated studies of nonuniversalities, flavor andCP violation in grand unified and string models will be carried out with the goal of achieving correlated predictions for the electric dipole moments of leptons and of flavor violating processes. This investigation is of importance in view of the proposed experiments for the sensitive search of the muon electric dipole moment and of the process mu-e+gamma.Studies of the amount of supersymmetric dark matter in the coannihilation region including effects of nonuniversalities will be carried out. Further, studies of dark matter under the influence of CP violationwill also be carrried out in the coannihilation region. Additional research will include investigations of new grand unified models which can remove the current constraint on such models brought about by the recent SuperKamiokande limit on the p-nubar+K mode. Such models include grand unified models with large representations and models in extra dimensions. Specifically the possible deduction of supergravity GUTswith a cascade from higher dimensional supergravity theories to lower dimensional ones along with supersymmetry breaking related to extra dimensions will be investigated.

将在超对称现象学、CP破坏、暗物质和额外维度等领域的理论高能物理及其在模型构建中的应用方面进行研究。布鲁克海文g-2实验和Tevatron的RUNII的数据对超对称性和超弦理论的影响将被探讨。我们将对大统一模型和弦模型中的非普适性、味性和CP破坏进行相关研究，目标是实现轻子电偶极矩和味破坏过程的相关预言。这项调查是非常重要的，鉴于建议的实验灵敏搜索的μ子电偶极矩和μ-e +gamma的过程。研究的超对称暗物质的量在共湮灭区域，包括非普遍性的影响将进行。此外，在CP破坏影响下的暗物质研究也将在共湮灭区进行。额外的研究将包括新的大统一模型的调查，可以消除目前的约束，这些模型所带来的最近的超级神冈极限的p-nubar+K模式。这些模型包括具有大表示的大统一模型和额外维度的模型。具体地说，我们将研究从高维超引力理论到低维超引力理论的级联沿着与额外维有关的超对称破缺的超引力GUTs的可能推导。
