The connections between string theory and gauge theory are becoming more evident each year. There have been continued explorations of the AdS/ CFT correspondence since its discovery a little less than 10 years ago. This correspondence relates String Theory to Conformal N=4 Supersymmetric Versions of Yang-Mills Theories. The PI proposes to understand from the field theory side how strings emerge from summing planar diagrams. The PI plans to sum open string planar diagrams in the light cone gauge. If he is successful in this endeavor for the N=4 super Yang-Mills theory he will try to use similar techniques to more realistic models of strong interactions such as large-N QCD and finally QCD itself. The broader impacts are that the PI will participate in the QuarkNet Center at Purdue in training high school teachers on current research ideas in physics. He will also give lectures at the Tindley Accelerated School which has a mostly minority student population. This research, if successful will elucidate the intriguing connection between String theory and the theory of strong interactions-QCD.

弦理论和规范理论之间的联系一年比一年明显。 自从不到10年前发现AdS/ CFT对应以来，人们一直在继续探索它。 这个对应关系将弦理论与杨-米尔斯理论的共形N=4超对称版本联系起来。PI提议从场论角度理解弦如何从求和平面图中出现。PI计划在光锥规范中求和开弦平面图。 如果他在N=4的超级杨-米尔斯理论的奋进中取得成功，他将尝试使用类似的技术来更现实的强相互作用模型，如大N QCD，最后是QCD本身。 更广泛的影响是，PI将参加普渡大学的QuarkNet中心，对高中教师进行有关物理学当前研究思想的培训。 他还将在廷德利加速学校讲课，该学校的学生主要是少数民族。这项研究如果成功，将阐明弦论和强相互作用理论QCD之间的有趣联系。
