Supersymmetry, Superstrings and Phenomenology

本提案的目标是在最深的亚核水平上寻找新的物理学，以提高我们对最高能量和宇宙早期阶段自然现象的理解。我们计划采用“自下而上”的超对称方法和自然界中可能隐藏的额外维度，以及“自上而下”的方法，其中所有粒子都被摇摆的弦取代，以寻求新的物理学，可以解释目前与中微子，暗物质和宇宙暗能量有关的实验观测，这项研究的结果不仅可以拓宽我们对宇宙中的力和物质的理解，而且还可以为宇宙的未来演化提供一个窗口。

The goal of the present proposal is to search for new physics at thedeepest subnuclear level in order to improve our understanding of naturalphenomena at the very highest energies as well as at the very early stagesof the universe. We plan to employ both the ``bottom-up''approach of supersymmetry and possible hidden extra dimensions in nature as well as the ``top down'' approach where all particles are replaced by wiggly strings to seek new physics that can explain present experimentalobservations related to neutrinos, dark matter and dark energy of theuniverse, origin of matter etc. The results of this study may not onlybroaden our understanding of the forces and matter in the universe but itmay also provide a window to its future evolution.
