Research in Particle Theory

研究理论高能物理的超对称现象学、CP破坏、暗物质和额外维度及其在模型构建中的应用。布鲁克海文g-2实验和Tevatron的RUNII数据对超对称和超弦理论的影响将被探索。在大统一模型和弦模型中进行非普适性、风味和cp违背的相关研究，目的是实现轻子电偶极矩和风味违背过程的相关预测。鉴于提出的灵敏搜索μ子电偶极矩和mu-e+ γ过程的实验，这一研究具有重要意义。研究超对称暗物质在共湮灭区域的数量，包括非普适性的影响。进一步，在共湮灭区域对CP违背影响下的暗物质的研究也将进行。额外的研究将包括对新的大统一模型的研究，这些模型可以消除最近对p-nubar+K模态的超级神冈极限所带来的对这些模型的当前约束。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。具体来说，我们将研究从高维超引力理论到低维超引力理论的级联超引力超广义相对论的可能推导，以及与额外维相关的超对称破缺。

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.
