String Theory from Gauge Theory

弦理论是规范和引力相互作用统一理论的候选者，从弦理论中推导出粒子物理的标准模型是一个挑战。主要原因是我们对弦理论的非微扰效应缺乏了解。在这里，为了理解非微扰效应和标准模型的推导，我们利用规范理论的描述来研究弦理论。我们研究的项目是(1)膜矩阵模型，(2)弦理论的E6大统一理论，(3)SU(2|2)光锥弦场理论和(4)ADS/CFT杨氏对称性。

It is a challenge to derive the standard model of particle physics from string theory, which is a candidate of the unified theory of gauge and gravitational interaction. The main reason is our lack of knowledge on the non-perturbative effect of string theory. Here aiming at the understanding of the non-perturbative effect and the derivation of the standard model, we study string theory using the gauge theory description. The projects we have studied are(1) the membrane matrix model,(2) the E6 grand unified theory from string theory,(3) su(2| 2) light-cone string field theory and(4) the AdS/CFT Yangian symmetry.
